Length of a rectangle is 4x²+12x and the area of the rectangle is 24x⁴+72x³, what is the width of the rectangle?

The width is

Step-by-step explanation:

The area of a rectangle is given as :

This implies that:

We have that the length is and the area is

We substitute to get:

We cancel out the common factors to get:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

part d
