What is the value of the expression: 3(4 + 2)?

To find the value of the expression 3(4 + 2), you need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Start by simplifying the expression inside the parentheses. Here, 4 + 2 equals 6. So, the expression can be rewritten as 3(6).

Next, you perform the multiplication. Multiply 3 by 6, which gives you 18.

Thus, the value of the expression 3(4 + 2) is 18. This matches the first answer choice.
