1. The problem asks which expression is equal to $12 + 20$. 2. First, calculate $12 + 20$: $$12 + 20 = 32$$ 3. Now, evaluate each option: - Option 1: $4 \cdot (0 + 5) = 4 \cdot 5 = 20$ - Option 2: $4 \cdot (3 + 5) = 4 \cdot 8 = 32$ - Option 3: $3 \cdot (4 + 5) = 3 \cdot 9 = 27$ - Option 4: $4 + (3 \cdot 5) = 4 + 15 = 19$ 4. Comparing these results to $32$, only Option 2 equals $32$. Therefore, the expression equal to $12 + 20$ is $4 \cdot (3 + 5)$.
