Ummm help plz and thank you

[tex] {4x}^{2} + 3x - 10[/tex]

1. Use foil method.

[tex] {4x}^{2} 5x + 8x - 10[/tex]

2. Collect like terms.

[tex] {4x}^{2} + ( - 5x + 8x) - 10[/tex]

3. Simplify.

[tex] {4x}^{2} + 3x - 10[/tex]

Therefor, the answer is.

[tex] {4x}^{2} + 3x - 10[/tex]

Answer:

(x+2)(4x−5)=4x2+3x−10.

Step-by-step explanation:

 multiply (x+2)(4x−5)

using FOIL.

((x)+(2))((4x)+((−1)5))=(x)⋅(4x)+(x)⋅((−1)5)+(2)⋅(4x)+(2)⋅((−1)5)=

=(4x2)+(−5x)+(8x)+(−10)=

=4x2+3x−10

Answer:

52.5

Step-by-step explanation:

Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:

The mean is 47.875 and the median is 51

Explanation:

To find the mean you have to add up all of the numbers together, and then divide that number (383) by how many numbers there are (8) so then you would get 47.875. Now you have to find the median. To find the median you have to place the numbers from the lowest to the greatest which would be 42, 51, 51, 51, 55, 64, 69. Then you basically just pick the number in the middle which is 51, so 51 is the median.

Answer:

35% off

Step-by-step explanation:

= |4 - 2.6|/((4 + 2.6)/2) = 1.4/3.3 = 0.42424242424242 = 42.424242424242%

Percentage of decrease = |4 - 2.6|/4 = 1.4/4 = 0.35 = 35%

2.6 is a 35% decrease of 4.

Answer:

Vertical Angles, the other answers are wrong, as they represents other angle orientations

Answer:

y=-2x+2

Step-by-step explanation:

Just follow the slope-intercept form formula-

Formula: y= mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Feel free to ask if you have any questions, hope this helps!(:

Answer:

M2+m3=90

Step-by-step explanation:

Angle 1 already is equal to 90. A triangle can only go up to 180 wo the other two angles have to add up to 90.

Answer:

1.06

Step-by-step explanation:

To the nearest hundredth, the answer is 1.06.

Answer:

x=13

Step-by-step explanation:

According to the question

3x+5x-14=90

8x-14=90

8x=90+14

8x=104

x=104/8

x=13

Answer:  c. 352.50 cm²

Step-by-step explanation:

Looking at the shape one can see that it is made up of 3 rectangles and 2 triangles.

The surface area will therefore be the sum of the areas of these 5 shapes.

Rectangle area = Length * width

= 7.5 * 13.5

= 101.25 cm²

There are 3 of them:

= 101.25 * 3

= 303.75 cm²

Triangles = 1/2 * base * height

= 1/2 * 7.5 * 6.5

= 24.375 cm ²

There are two of them:

= 24.375 * 2

= 48.75cm²

In total:

= 303.75 + 48.75

= 352.50 cm²

Answer:

i dont get it

Step-by-step explanation:

Answer:

mn = k

Step-by-step explanation:

Given that,

m is inversely proportional to n.

ATQ,

[tex]m\propto \dfrac{1}{n}[/tex]

or

[tex]m=\dfrac{k}{n}[/tex]

Cross multiplying both sides,

mn = k

Hence, the required equation is "mn=k".

Answer:

E

Step-by-step explanation:

E is the correct answer

Answer:

Step-by-step explanation:

Given

Conjugate of z is:

Product zz' is:

If ,

[tex]\bold{z=-3+5i }[/tex]

so,conjugate of z

[tex]\overline{ z }[/tex]=[tex]\bold{-3-5i }[/tex]

Because, in argand plane [tex]\overline{ z }[/tex] is the reflection of z in x-axis.

so,

According to the question,

z[tex]\overline{z}[/tex]=(-3+5i)(-3-5i)

[tex]\bold{(-3)^2-(5i)^2 }[/tex]

[tex]\bold{9-25(-1) }[/tex]

[tex]\bold{ 9+25 }[/tex]

Answer:

D.  x>[4]

Plzzzzz give me Brainliest!!!!!  

Answer:

D. x > 4

Step-by-step explanation:

You have to do the opposite operations to get the variable on one side of the equation by itself.

4 - x + 4 = 8 - 4

x = 4

You only switch the comparison sign if you mutliply or divide by negative numbers when you do opposite operations to get the variable on one side of the equation by itself.

I hope this helps!

Answer: (MAKE ME BRAINLIST PLEASE)

Answer: For Abigail W = $5t

For her younger sibling W= $3t

Bit by bit clarification:

How about we address the compensation with W

t as the time spent on work in hours

Abigail will be paid $5 every hour, her all out compensation will be

W(abg) = $5t

Her younger sibling will be paid $3 every hour, her complete compensation will be

W(lts) = $3t

Step-by-step explanation:

y-intercept in the point x = 0

B) is the easiest

g(x) or y value

g(x) = 3x² + 6x -9

= 3(0)² + 6(0) -9

= 0 + 0 -9

= -9

y-intercept = (0,-9)

Answer:

angle v equals 75.8 degrees

Step-by-step explanation:

since the lines parallel, then angle u and angle v would be the same as they are alternate interior angles. you can also subtract 180 with angle w to find angle v as well (180 - 104.2 = 75.8)
