Which expression represents the following calculation? Add 450 to 348 , and then multiply by 7 . Q \( 450+348 \times 7 \) \( (450+348) \times 7 \) \( 450 \times 7+348 \)

To determine which expression correctly represents the calculation "Add 450 to 348, and then multiply by 7," we need to break down the steps: 1. **Add 450 to 348**: This part of the calculation can be represented as \( 450 + 348 \). 2. **Multiply the result by 7**: After adding, we then multiply the sum by 7, which can be represented as \( (450 + 348) \times 7 \). Now, let's analyze the given options: - **Option Q**: \( 450 + 348 \times 7 \) - This implies that 348 is multiplied by 7 first, which is not what we want. - **Option 1**: \( (450 + 348) \times 7 \) - This correctly represents adding 450 to 348 first and then multiplying the result by 7. - **Option 2**: \( 450 \times 7 + 348 \) - This implies that 450 is multiplied by 7 first, and then 348 is added, which is also not what we want. Thus, the correct expression that represents the calculation is: \[ (450 + 348) \times 7 \]
