Answer:
D
Step-by-step explanation:
R(x) = -x^2+122x+400
Well the area of a trapezoid is defined by the following formula:
A =

where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.
Let's plug in what we know into this formula:
h = 7 the perpendicular distance between the two bases
b₁ = 15 the shorter parallel side
b₂ = 25 the longer parallel side made up of 4 + 15 + 6
so, A =

This is in square units of measure of course, so 140 in²
G-13=7 the answe is 20 if you just making a equation would have been more help w a pic or something
I believe it's 8 because it's scale is 4 times bigger.
2×4=8
