The area, a, of a rectangle is 120x2 + 78x – 90, and the length, l, of the rectangle is 12x + 15. which of the following gives the width, w, of the rectangle?

Width = 2(5x - 3)

Step-by-step explanation:

The area A, of the rectangle, is given by 120x² + 78x - 90.

Now, the area can be expressed as 6(20x² + 13x - 15)

= 6(20x² + 25x - 12x -15)

= 6(4x + 5)(5x - 3).

Now, the length of the rectangle is given by (12x + 15) = 3(4x + 5)

So, the width of the rectangle = (Answer)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
