Question

Which expression has a value of 32 when m = 8?
m – 8
4m
StartFraction m Over 2 EndFraction
m + 8

Answer 1

To find the expression that has a value of 32 when \( m = 8 \), we can evaluate each expression one by one:

1. **For \( m - 8 \)**:
\[
8 - 8 = 0
\]

2. **For \( 4m \)**:
\[
4 \cdot 8 = 32
\]

3. **For \( \frac{m}{2} \)**:
\[
\frac{8}{2} = 4
\]

4. **For \( m + 8 \)**:
\[
8 + 8 = 16
\]

From the evaluations above, only \( 4m \) has a value of 32 when \( m = 8 \).

Thus, the expression that has a value of 32 when \( m = 8 \) is **\( 4m \)**.
