Final answer:
To calculate the expression 17 + 7^2 / (17 - 2 * 7), follow the order of operations. The correct answer is C) 20.
Step-by-step explanation:
To calculate the expression 17 + 7^2 / (17 - 2 * 7), we need to follow the order of operations, also known as PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction).
First, we calculate the exponent: 7^2 = 49.
Next, we calculate the multiplication: 2 * 7 = 14.
Then, we calculate the subtraction: 17 - 14 = 3.
Finally, we perform the division: 49 / 3 = 16.33.
Next, we add 17 to the result: 17 + 16.33 = 33.33.
Therefore, the correct answer is C) 20.
