Question

peyton says the expressions $5(3 + x)$ and $15 + x$ are equivalent. evaluate $5(3 + x)$ when $x = 0$. $5(3 + x) = 5(3 + 0) = \square$

Explanation:

Step1: Substitute x=0

We substitute \( x = 0 \) into the expression \( 5(3 + x) \), getting \( 5(3 + 0) \).

Step2: Simplify inside the parentheses

First, simplify the expression inside the parentheses: \( 3 + 0 = 3 \). So now we have \( 5\times3 \).

Step3: Multiply

Calculate \( 5\times3 = 15 \).

Answer:

15
