iris [78.8K]

Answer:  x - 5

Step-by-step explanation:

Since, the area of the rectangle = x^2 - 25=(x+5)(x-5)

Length of the rectangle = x+5

Let the width of the rectangle = b

Thus, the area of the rectangle = (x+5)\times b

⇒ (x+5)\times b=(x+5)(x-5)

⇒  b=\frac{(x+5)(x-5)}{(x+5)}

⇒ b=x-5

Therefore, the expression that shows the width of the rectangle = x-5
