Question

The area of a rectangle is represented by 63x^{3}+9x and the length is represented by 7x^{2}+1 . Find the width of the rectangle in terms of x.

Answer 1

Explanation:

`7x^(2) +1 = 15x` and
`63x^(2) +9x= 135x`

so, divide because to solve for area you multiply so the opposite of multiplication is division, Anyway so
`135x/15x=9x`

Hope this helps.
