To find: The width of the rectangles.
Answer to Problem 64PFA
C is the correct option.
Explanation of Solution
Given:
The areas of two rectangles whose width are equal are
Calculation:
The area of the first
Find the factored form of this expression
Make group as shown below
Now, factored out the GCF from each group
Now, factored out the common term
Similarly, find the factored form of the second polynomial
Now, the area of the rectangle is the product of length and width. And since the width of both the rectangles are equal.
Hence, the width will be the factor common in both of the factored form.
Thus, the width of the rectangles is
