Answer:
area = length x width
x² - 25 = x + 5 · width
(x - 5)(x + 5) = (x + 5)w
(x - 5)(x + 5) / (x + 5) = (x + 5)w / (x + 5)
x - 5 = w
Step-by-step explanation:
1. write down the formula of area.
2. since the area is a difference of squares, factor them into two binomials, and replace the length by its measure. you can use w for width
3. to get width, divide the one of the binomials with the length that matches together to get w.
