If the area of the rectangle shown below is given by the expression 3x2 + 7x – 6, and the width is (x + 3), which of the following could represent the length?

Step-by-step explanation:

3x² + 7x - 6 = 3x² + 9x - 2x - 2*3

                  = 3x (x + 3) - 2(x +3)

                  = (3x - 2)(x + 3)

Area of the rectangle = 3x² + 7x - 6

length * width = 3x² + 7x - 6

length * (x + 3) = (3x -2)(x +3)

          length =

          length = (3x - 2)
