What is the value of x?
Enter your answer in the box.

x = ___

x is equal to seven.

Step-by-step explanation:

because the two horizontal lines are parallel, the ratios of the side segments between them will be the same.

That means you can say:

(2x + 10) / 3 = 40 / 5

(2x + 10) / 3 = 8

2x + 10 = 24

2x = 14

x = 7

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
