Question

The width w of a rectangular swimming pool is 7x2. The area A of the pool is 7x3 – 42x2. What is an expression for the length of the pool?

Answer 1

(7x^3 – 42x^2) /(7x^2) ?

Answer 2

Area(A) = 7x^3 – 42x^2 = 7x^2(x-6)

Answer 3

width(w) = 7x^2

Answer 4

Medal, if you justify that, Corey :)

Answer 5

Area = width*length
Area/width = length
or
[7x^2(x-6)]/[7x^2] = length
(x-6) = length
x-6 = length (this is what they're looking for)

Answer 6

Totally worth it :)

Answer 7

NP (:
