Yes, because if you have x=5 and x=10 they are parallel lines to each other.
Answer:
The first step is to slove the numbers in the brackets
Step-by-step explanation:
[(x+7) x -2] / 4 = 7
-2(x+7) / 4 = 7
-2x-14 / 4 = 7
-2x-14 = 28
-2x = 42
x = -21
PEMDAS
By comparing the perimeters, we can deduce the scaling factor:

The areas scale with the square of the scaling factor, so the new area is
