Question

If a rectangle has a area of 36x^3+24x^2-18x and the width is 6x what is the length

Answer 1

`lenght= 6 {x}^(2) + 4x - 3`

Explanation:

`lenght = (area)/(width) \\ \\ = \frac{36 {x}^(3) + 24 {x}^(2) - 18x }{6x} \\ \\ = \frac{6x(6 {x}^(2) + 4x - 3) }{6x} \\ \\ lenght= 6 {x}^(2) + 4x - 3`
