b) 21

c) -15

d) 33

Answer 1

To evaluate the expression 57 - 6^2 ÷ (2 + 1) × 4, we follow the order of operations and get the answer 48.

Step-by-step explanation:

To evaluate the expression 57 - 6^2 ÷ (2 + 1) × 4, we follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and finally Addition and Subtraction (from left to right).

1. First, we evaluate the exponent 6^2, which is 36.
2. Next, we evaluate the expression inside the parentheses (2 + 1), which is 3.
3. Then, we divide 36 by 3, which gives us 12.
4. Finally, we multiply 12 by 4, which gives us the final answer of 48.

Therefore, the correct answer is d) 33.
