Question

The rectangle below has an area of x^2 - 4x - 12square meters and a length of x +2 meters.

What expression represents the width of the rectangle?
Width = ____ meters

Answer 1

The area is the product of length times width. If you know the area and the length, you can find the width by dividing the area by the length.

Divide x+2 into x^2 - 4x - 12. In your shoes I would use synthetic division, but long division would work fine also. please show your work; if you do, I'll comment on it.
