The area of the trapezoid is 14 square feet. Write an equation that you can use to find the value of x. An equation is __ = 14.

Someone please help!

The area is base Plus times height divided by 2

the area = (x + 2x ) x 2 x 1/2 = 3x .

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
