Answer:
The answer is 4a
Step-by-step explanation:
1) Simplify 4a² + 12a² to 16a².
[tex] \sqrt{ {16a}^{2} } [/tex]
2) Use this rule:
[tex] \sqrt{ab} = \sqrt{a} \sqrt{b} [/tex]
[tex] \sqrt{16} \sqrt{ {a}^{2} } [/tex]
3) Since 4 × 4 is 16, the square root of 16 is 4.
[tex]4 \sqrt{ {a}^{2} } [/tex]
4) Simplify.
[tex]4a[/tex]
Therefor, the answer is 4a.
Rewrite and simplify. 64-3/4
Answer:
64 - .75
64 - .75 = 63.25
have a good day/night
Answer: 63.25 (Decimal) or 63 1/4 (fraction)
Step-by-step explanation: 64 - 3/4. 3/4 is 0.75 in decimal form, so subtracting it would be 63.25 which would be 63 1/4 in fraction form. I don’t think you can simplify it since 1/4 is already at it’s smallest form.

Hello there! The value of x is 20 or -20
"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.
Step-by-step explanation:
[tex] \large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }[/tex]
First, we simplify 5² and 4²
[tex] \large{ \frac{ {x}^{2} }{25} = 16}[/tex]
Multiply the whole equation by 25 to get rid of the denominator.
[tex] \large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}[/tex]
Square both sides and solve the equation.
[tex] \large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}[/tex]
Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.
[tex] \large{x = \pm{20}}[/tex]

The picture shows the letter H that is on a store sign.
3 in.
9 in.
3 in.
3 in.
3 in.
3 in.
What is the area of this letter H? Enter the answer in the box.
square inches
Answer:
[tex]63in^2[/tex]
Step-by-step explanation:
To find the area of the larger, complex figure, divide the shape up into smaller figures, solve for the area of each smaller part and then add up the answers to find the total area. The figure can be divided into two rectangles and a square.
The two rectangles are congruent, their dimensions are the following,
9in x 3in
The area of the square is the following,
3in x 3in
To find the area of both of these figures, one uses the formula,
[tex](length)(width)[/tex]
Substitute in each dimension and solve for the total area by adding up the results,
[tex]((9)(3))+((9)(3))+((3)(3))\\\\=(27)+(27)+(9)\\\\= 63[/tex]

Answer:
7
Step-by-step explanation:
Note the values on the right are 7 times the corresponding value on the left side, that is
15 × 7 = 105
12 × 7 = 84
4 × 7 = 28
Then
1 × 7 = 7 ← required value
Answer:
7 or B
Step-by-step explanation:
28/4=7
12*7=84
7 is the number you multiply the first row by to get tbe second row. 1*7=7

Answer:
The second option is correct.
Step-by-step explanation:
If x = 5, then this happens.
1(5) - 2 < 3
5 - 2 < 3
3 < 3
That is incorrect because 3 = 3.
The second option is correct, because:
4 - 2 < 3
2 < 3
This work so the second option is correct

question
(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!
Answer:
(60-5.8) ÷ 5 - 3² = 1.84 (approx)
Step-by-step explanation:
(60-5.8) ÷ 5 - 3²
First simplify the numbers inside the bracket.
(60-5.8) = 54.2
Now, the equation is in the form of,
54.2 ÷ 5 - 9
Put 54.2 ÷ 5 in a bracket for easy calculation.
(54.2 ÷ 5) - 9
Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84
Subtract 9 from 10.84
10.84 - 9
You will now get the answer as,
1.84 (approx)
Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1 and 3 over 4 pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1\frac{3}{4} pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?
Answer:
$8.75
Step-by-step explanation:
STEP TO TAKE TO DETERMINE THE ANSWER
Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5
[tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]

Step-by-step explanation:
The diagram shows a solid metal cuboid.
The areas of three of the faces are marked on
the diagram.
The lengths, in cm, of the edges of the cuboid
are whole numbers.
The metal cuboid is melted and made into cubes.
Each of the cubes has sides of length 2.5 cm.
Work out the greatest number of these cubes that can be made.
You must show your working.
Answer:
6 cubes
Step-by-step explanation:
Considering the given cuboid, it can be deduced that;
length of the cuboid = 7 cm
width of the cuboid = 3 cm
height of the cuboid = 5 cm
Thus,
volume of the cuboid = length x width x height
= 7 x 3 x 5
= 105 cubic centimetres
The cubes has sides of length 2.5 cm.
volume of each cube = length x width x height
= 2.5 x 2.5 x 2.5
= 15.625 cubic centimetres
The greatest number of cubes that can be made = [tex]\frac{105}{15.625}[/tex]
= 6.72
The greatest number of cubes that can be made from the cuboid is 6.

David has earned the following test
grades: 89, 96, 99, 85. What is the
grade David has to earn on his 5th test to maintain a test
average of 90?
Answer:
81
Step-by-step explanation:
Required average= 90
let the required grade be x
Average= Sum of n numbers
90= 89+96+99+85+x divide by 5
450= 369+x
x = 450-369
x=81
