Your answer is 4. 2^2 is 4 and you minus 8 by that 4.
Answer:
answer in the screen shot provided
General equation of line
y = mx + c
Since this line is parallel to y=7x-8
m=7
y = 7x + c
If point (5,-2) is in that line,
-2 = (7*5) + c
-2 = 35 + c
c = -37
so the equation is
y = 7x + -37
Length: 4x
Width: ??
Length x Width: 4x^2 + 12x
Can be rewritten as: 4x(x+3)
Therefore: ?? = x + 3
