(2 × 9) + (2 × 3)
please help
me with this someone
To solve the expression 2(9 + 3), you need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, evaluate the expression inside the parentheses: 9 + 3 = 12.
Next, multiply 2 by the resulting value: 2 × 12 = 24.
Therefore, the correct answer is: 2(9 + 3) = 24.
Out of the given options:
- (2 × 9) − (2 × 3) = 18 - 6 = 12 (not the correct answer)
- (2 × 9) + (9 × 3) = 18 + 27 = 45 (not the correct answer)
- (2 × 9) + 3 = 18 + 3 = 21 (not the correct answer)
- (2 × 9) + (2 × 3) = 18 + 6 = 24 (not the correct answer)
None of the provided options is the correct answer. The correct answer is simply 24.
To solve the expression 2(9 + 3), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Start by simplifying the expression inside the parentheses.
9 + 3 = 12
Step 2: Multiply 2 by the simplifed expression.
2 * 12 = 24
Therefore, the answer is 24.
So the correct answer is:
(2 × 9) + (2 × 3)
