Explanation:

Step1: Multiply 9 and 7a

To find the area of the first rectangle (with side lengths 9 and 7a), we use the formula for the area of a rectangle, \( \text{Area} = \text{length} \times \text{width} \). So, \( 9\times7a = 63a \).

Step2: Multiply 9 and -5

To find the area of the second rectangle (with side lengths 9 and -5), we again use the area formula. So, \( 9\times(-5)= -45 \).

Answer:

The missing values are \( 63a \) (for the top rectangle) and \( -45 \) (for the bottom rectangle). When expanding \( 9(7a - 5) \), we get \( 63a - 45 \).
