The rectangle below has an area of x2 6x 7 square meters and a width of x 7 meters What expression representsthe length of the rectangle class=

Respuesta :

Answer:

The length is (x+1)

    Step-by-step explanation:

We know the area equals length times width. LxW=Area

We know the width equals (x-7). We also know the area equals x² - 6x - 7.

We need to expand the area. When we do, we get (x+1)(x-7).

The width is (x-7), so the length must be (x+1)
