p + 3

Answer 1

To determine which expression has a value of 15 when \( p = 12 \), we can evaluate each expression one by one.

1. **First expression: \( \frac{18}{p} \)**
\[
\frac{18}{p} = \frac{18}{12} = 1.5
\]

2. **Second expression: \( 3p \)**
\[
3p = 3 \times 12 = 36
\]

3. **Third expression: \( 18 - p \)**
\[
18 - p = 18 - 12 = 6
\]

4. **Fourth expression: \( p + 3 \)**
\[
p + 3 = 12 + 3 = 15
\]

The only expression that has a value of 15 when \( p = 12 \) is:
\[
\boxed{p + 3}
\]
