Answer:
C. y = x^2 + 4x.
Step-by-step explanation:
Area of a trapezoid = (h/2)(a + b) where h is the altitude and a and b are the lengths of the parallel sides.
So here
Area y = (x/2)(8 + 2x)
= 8x/2 + 2x^2/2
= 4x + x^2.
Answer: x - 5
Step-by-step explanation:
Since, the area of the rectangle =
Length of the rectangle = x+5
Let the width of the rectangle = b
Thus, the area of the rectangle =
⇒
⇒
⇒
Therefore, the expression that shows the width of the rectangle = x-5
