Question

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

Explanation:

Step1: Substitute x with 0

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

Step2: Perform the addition

Now we calculate \(15 + 0\). According to the addition property of zero, any number added to zero is the number itself. So \(15+0 = 15\).

Answer:

\(15\)
