What is the value of 3(4-7) - 6^2?

1. -25

2. -9

3. 3

4. 6

The correct answer is: -25

To solve the expression 3(4-7) - 6^2, we start by simplifying within the parentheses. The operation inside the parentheses is 4 - 7, which equals -3. Next, we multiply this result by 3: 3 * (-3) = -9. Now, we need to assess the second part of the expression, which is 6 raised to the power of 2: 6^2 = 36. Now we combine the two parts we calculated: -9 - 36. Subtracting gives us: -9 - 36 equals -45. Therefore, the value of the entire expression 3(4-7) - 6^2 simplifies to -45. Considering the multiple choices and the correct calculations, the value is not aligned with choice A. The correct calculation shows that the answer is indeed different from what was suggested.
