Question

1. which expression represents \9 less than the product of 5 and a number n\? a. 9 - (5 + n) b. 9 - 5n c. (5 + n) - 9 d. 5n - 9 8. which expression represents \the sum of 16 squared and the quotient of 8 and a number b\? a. 16² + \frac{8}{b} b. 16² + 8b c. (16 + 8)² + b d. (16 + 8 ÷ b)²

Explanation:

Question 7

Step1: Analyze the phrase "the product of 5 and a number \( n \)"

The product of 5 and \( n \) is \( 5 \times n = 5n \).

Step2: Analyze "9 less than the product"

"9 less than" a quantity means we subtract 9 from that quantity. So, 9 less than \( 5n \) is \( 5n - 9 \).

Step1: Analyze "16 squared"

16 squared is \( 16^2 \).

Step2: Analyze "the quotient of 8 and a number \( b \)"

The quotient of 8 and \( b \) is \( \frac{8}{b} \).

Step3: Analyze "the sum of 16 squared and the quotient"

The sum means we add the two quantities, so it is \( 16^2 + \frac{8}{b} \).

Answer:

D. \( 5n - 9 \)
