Question

evaluate each expression if d = 8, e

1. 2(d + 9)

show your work.

Explanation:

Step1: Substitute \( d = 8 \) into the expression

We have the expression \( 2(d + 9) \). Substitute \( d = 8 \) into it, so we get \( 2(8 + 9) \).

Step2: Calculate the value inside the parentheses

First, calculate the sum inside the parentheses: \( 8 + 9 = 17 \). Now the expression becomes \( 2\times17 \).

Step3: Multiply the two numbers

Multiply 2 and 17: \( 2\times17 = 34 \).

Answer:

34
