Which expression is equivalent to 3 (4 + 5) - 2 × 6 2
There are different ways to approach this problem, but one common method is to use the order of operations (also known as PEMDAS) and simplify each operation in the correct order:
1. Start with the parentheses: 4 + 5 = 9.
2. Multiply 2 × 6 = 12.
3. Multiply 3 × 9 = 27.
4. Subtract 12 from 27 = 15.
Therefore, 3 (4 + 5) - 2 × 6² is equivalent to 15.
