Question

evaluate $15 + x$ when $x = 0$.
$15 + x = 15 + \square$

Explanation:

Step1: Substitute x with 0

We know that \( x = 0 \), so we substitute \( x \) in the expression \( 15 + x \) with 0. So \( 15 + x = 15 + 0 \).

Step2: Determine the value to fill

The blank in \( 15 + \square \) should be filled with the value of \( x \), which is 0.

Answer:

0
