The correct Answer is:
To evaluate the expression `(-15) × 8 + (-15) × 2`, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Expression**: We have the expression `(-15) × 8 + (-15) × 2`. 2. **Apply Multiplication**: First, we will multiply `-15` by `8`. \[ -15 × 8 = -120 \] 3. **Apply Multiplication Again**: Next, we will multiply `-15` by `2`. \[ -15 × 2 = -30 \] 4. **Combine the Results**: Now we will add the two results together: \[ -120 + (-30) \] 5. **Simplify the Addition**: Adding two negative numbers results in a more negative number: \[ -120 - 30 = -150 \] ### Final Answer: The value of the expression `(-15) × 8 + (-15) × 2` is \(-150\). ---
