Q. Evaluate the expression for

h = -15

.

\newline

3 + h =

_____

Identify Expression: Identify the expression to evaluate. $\newline$ We are given the expression $3 + h$ and the value of $h$ as $-15$ . We need to substitute $-15$ for $h$ in the expression.
Substitute Value: Substitute $-15$ for $h$ in the expression. $\newline$ The expression becomes $3 + (-15)$ .
Evaluate Expression: Evaluate the expression $3 + (\text{–}15)$ . Adding a negative number is the same as subtracting its absolute value. So, $3 + (\text{–}15)$ is the same as $3 - 15$ , which equals $\text{–}12$ .
