Triangle XYZ has vertices at (2, 6), (4, -2), and (-2, -8) and is dilated to form a new triangle. Triangle, X'Y'Z', has vertices at (1, 3), (2, -1), and (-1, -4). What scale factor was applied to XYZ to create X'Y'Z'?

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
