The answer is...
x^3 + 6y^3
I think it is B i hope this helped
Step-by-step explanation:
24% is the same as 6/25
<span>A. give the coordinate of F and H in terms of a
Given
E (0,0) and G (8,8)
H (8, [8-a])
F ([8 - a], 8)
</span><span>B. using the coordinate of E, F, G, and H, find the slope of EG and FH. show your work
Line EG
</span>E (0,0) and G (8,8)
slope = 8/8 = 1
Line FH
H (8, [8-a]) and F ([8 - a], 8)
slope = (8 - a - 8) / (8 - [8-a])
slope = (8 - a - 8) / (8 - 8 + a)
slope = -a/a
slope = -1
<span>C. use part B to prove that EG _|_ FH
Line </span>EG has slope = 1 and line FH has slope = -1
Slopes are negative and reciprocal so the line EG is perpendicular to line FH.

Answer:
(b) 38.5
Step-by-step explanation:
The polygon is a trapezoid with bases 4 and 7 and height 7. Its area is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(4 +7)(7) = 77/2
A = 38.5 . . . . square units
