What is the result of 9 + 3(2² - 4)?

What is the result of 9 + 3(2² - 4)?

• A. 5
• B. 9
• C. 12
• D. 15

Answer: (B)

To solve the expression \(9 + 3(2² - 4)\), we need to follow the order of operations, often abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). 1. Begin by evaluating the expression inside the parentheses: \(2² - 4\). - First, calculate \(2²\) which equals \(4\). - Next, subtract \(4\) from that result: \(4 - 4 = 0\). 2. Now substitute back into the expression, which simplifies to \(9 + 3(0)\). 3. Next, calculate \(3(0)\): - This results in \(0\). 4. Finally, add this result to \(9\): - \(9 + 0 = 9\). Thus, the result of the expression \(9 + 3(2² - 4)\) is \(9\), confirming that the answer is indeed the correct one.

To solve the expression (9 + 3(2² - 4)), we need to follow the order of operations, often abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Begin by evaluating the expression inside the parentheses: (2² - 4).

• First, calculate (2²) which equals (4).

• Next, subtract (4) from that result: (4 - 4 = 0).

2. Now substitute back into the expression, which simplifies to (9 + 3(0)).

3. Next, calculate (3(0)):

• This results in (0).

4. Finally, add this result to (9):

• (9 + 0 = 9).

Thus, the result of the expression (9 + 3(2² - 4)) is (9), confirming that the answer is indeed the correct one.
