Answer: C x = -2
Step-by-step explanation:
[tex]3x^{2} - 30x - 72 = 0[/tex]
[Add 72 on both sides]
[tex]3x^{2} - 30x = 72[/tex]
[Factorise Left Hand Side of equation to get 3 on one side of a bracket]

[Divide each side by 3 to just get the brackets and the x's on one side]
[tex]x^{2} -10x = 24[/tex]
[Minus 24 on both side as the equation must = 0]
[tex]x^{2} -10x-24=0[/tex]
[Solve the square on the left hand side]

[Solve for x on left hand side - two possible answers]

Diane cycled a total distance of 71,808 feet on a bicycle path surrounding a lake she cycled eight laps where each lap was the same length what was the length of each lap around the lake
The length of each lap around the lake is 8976 feet.
We are informed that Diane cycled 8 laps around the lake. Also, Diane covered total distance of 71,808 feet. So, length of 8 laps = total distance covered by Diane. Hence, the length of each lap will be calculated by performing division.
Length of 1 lap = total distance covered by Diane ÷ length of 8 laps
Keep the values in formula to find the length of each lap.
Length of each lap = 71,808 ÷ 8
Performing division to find the length of each lap
Length of each lap = 8976 feet
Thus, the length of each lap around the lake is 8976 feet.

9. The volume of a box in cubic feet can be expressed as V(x) = x³ - 3x² - 10x or as the product of three linear factors with integer coefficients. The width of the box is 5-x. What is the length, width, and height of the box in factored form? A. -x(5-x)(x+2) B. X(5-x)(x+2) C. X(5-x)(x-2) D. -x(5-x)(x-2)
The length, width, and height of the box in factored form is -x (x-5)(x +2) which is option A
The box is in the shape of a cuboid
The volume of a cuboid = l b h, where l is the length, b is the breath or width and h is the height
Putting the values of width and volume in the formula
x³ - 3x²-10x = l ×(5-x) × h
This becomes a cubic equation
l × h = (x³-3x²-10x)/ 5-x
l × h = -x²-2x
l × h = -x(x+2)
Now, putting the value of l × h in the equation we get
v= -x ( x+ 2) (5-x)
v = -x (x-5)(x +2)
Hence, the length, width, and height of the box in factored form is -x (x-5)(x +2) which is option A

Of the 200200 parking spaces in a parking lot, 6\%6% of the spaces are reserved for handicapped parking. Of those parking spaces NOT reserved for handicapped parking, 2020 are suitable for compact cars only. How many spaces that are NOT reserved for handicapped parking are suitable for non-compact cars?
Using proportions, it is found that 38 spaces are suitable for non-compact cars.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have that:
94% of the spaces are not reserved for handicapped parking, hence this number is of 0.94 x 200 = 188.Of those, 20% are suitable for compact cars, hence 0.2 x 188 = 38.38 spaces are suitable for non-compact cars.

Suppose M is the midpoint of FG. Find the missing measure FM = 3x - 4, MG = 5x - 26
Answer:
FG=58 X=11
Step-by-step explanation:
I'm assuming your looking for the whole segment. What I did was 3x-4=5x-26. We first have to find X. So just use the equation to find X. You should get X=11 if you did it the way I set it up. Then you plug it in with the measures you got. So FM = 3(11)-4 and 5(11)-26. You should get 29 for both. If your looking for FG, you would add those two together. So 29+29= 58. FG=58. there you go.
I converted 600 kcal into units of btu, joules, and kwh. the answers were 0.70, 2380, and 2.51x106; except i forgot which number goes with which units. what is the correct pairing of values and units?
600 kcal, when converted, is equivalent to 2380 BTU, 2.51 x 10^6 joules, and 0.70 kwh.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume, etc. to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
kcal, BTU, joules, and kwh are all units of energy. To convert kcal to these units, we can use the following conversions:
1 kcal = 3.96567 BTU
1 kcal = 4184 joules
1 kcal = 0.00116222 kwh
Converting 600 kcal to BTU, joules and kwh:
1 kcal = 3.96567 BTU
600 kcal = 600(3.96567 BTU)
600 kcal = 2379.4 BTU ≅ 2380 BTU
1 kcal = 4184 joules
600 kcal = 600(4184 joules)
600 kcal = 2.51 x 10^6 joules
1 kcal = 0.00116222 kwh
600 kcal = 600(0.00116222 kwh)
600 kcal = 0.697333 kwh ≅ 0.70 kwh

simplify: 3/x+1 - 1/x-1 - 2x/x^2+1
The simplified expression of 3/x+1 - 1/x-1 - 2x/x^2+1 is [-2x^3 - 4x^2 + 2x - 2]/[x^4 - 1]
How to simplify the expression?The expression is given as
3/x+1 - 1/x-1 - 2x/x^2+1
Take the LCM of the first two terms
So, we have
(3x - 3 - x - 1)/(x^2 - 1) - 2x/x^2+1
This gives
2x - 4/(x^2 - 1) - 2x/x^2+1
Take the LCM
[(2x - 4)(x^2 + 1) -2x(2x^2 - 1)]/(x^4 - 1)
Expand
[2x^3 - 4x^2 + 2x - 4 - 4x^3 + 2]/[x^4 - 1]
Evaluate the like terms
[-2x^3 - 4x^2 + 2x - 2]/[x^4 - 1]
Hence, the simplified expression of 3/x+1 - 1/x-1 - 2x/x^2+1 is [-2x^3 - 4x^2 + 2x - 2]/[x^4 - 1]

Applying the definition of supplementary angles, x = 18; m<PNO = 70°.
What are Supplementary Angles?If two angles lie on a straight line adjacent to each other, both angles are supplementary, thus, their sum is equal to 180 degrees.
Angle MNO and angle PNO are supplementary angles, therefore:
m<MNO + m<PNO = 180 degrees.
m<MNO = 110°
m<PNO = (3x + 16)°
Substitute
110 + 3x + 16 = 180
126 + 3x = 180
126 + 3x - 126 = 180 - 126
3x = 54
x = 18
m<PNO = 3x + 16 = 3(18) + 16
m<PNO = 70°
Therefore, applying the definition of supplementary angles, x = 18; m<PNO = 70°.

The points (–5, 4) and (9, –2) are on a line. Find the intercepts to the nearest tenth.
Answer:
The y-intercept = (0, 13/7).
The x-intercept = (13/3, 0).
To the nearest tenth they are
y-intercept (0, 1.9)
x-intercept (4.3, 0)
Step-by-step explanation:
First find the equation oif the line joining these points:
Slope of line = (4 - (-2)) / (-5-9))
= 6/-14
= -3/7
y - y1 = m(x - x1)
Using m = -3.7 and (x1, y1) = (-5, 4)
y - 4 = -3/7(x - (-5)
y = -3/7x -15/7 + 4
y = -3/7x + 13/7 is the equation of the line.
The y-intercept (when x = 0)
= 0 + 13/7
= (0, 13/7)
The x-intercept:
0 = -3/7x + 13/7
x = -13/7 / -3/7
= 13/3.
x intercept is (13/3, 0)

The length of the NFL playing field is 100 yards and the width is 30 yards.
What is perimeter?
The perimeter of an object is the distance round the shape or object.
The perimeter of a shape is obtained by summing length and width of the shape in two places.
P = 2(L + W)
where;
L is the length of the shapeW is the width of the shapeFrom the given question,
L = 2W + 40
260 = 2(L + W)
260 = 2(2W + 40 + W)
260 = 2(3W + 40)
260 = 6W + 80
260 -80 = 6W
180 = 6W
180/6 = W
30 = W
L = 2W + 40
L = 2(30) + 40

The maximum capacity of a container which can measure the kerosene oil of both the tankers when used an exact number of times is 170 Litres.
Amount of kerosene in first tanker = 850 litres
Amount of kerosene in Second tanker = 680 litres
The maximum capacity of a container which can measure the kerosene oil of both the tankers when used an exact number of times will be the HCF of amount of kerosene in first tanker and amount of kerosene in second tanker i.e., HCF of 850 litres and 680 litres.
To calculate HCF of 850 and 680 , we can write

Answer:

Step-by-step explanation:
By comparing the sides of the triangles,
we take the ratio of each sides to each other
de/cb = fe/ca
de.ca = fe.cb
fe = (de.ca)/cb
fe = (7* 18)/14
fe = 9
The measure of side FE of triangle DEF is FE = 9
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ABC
Now , let the second triangle be DEF
And triangle ABC and DEF are similar triangles
So , corresponding sides of similar triangles are in the same ratio
And , AE = EB and CF = FB
From the similar triangle theorem ,
EF / AC = DE / CB
Substituting the values in the equation , we get
EF / 18 = 7 / 14
Multiplying by 18 on both sides of the equation , we get
EF = ( 7 x 18 ) / 14
EF = 18/2
EF = 9
Therefore , the value of EF is 9
Hence , the measure of side EF is 9
