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

To find the value of the expression 2(x + 3) when x = 4, you start by substituting the value of x into the expression.

First, replace x with 4 in the expression:

2(4 + 3)

Now, perform the operation inside the parentheses:

4 + 3 equals 7.

Next, multiply the result by 2:

2 * 7 = 14.

The final value of the expression is 14. This matches the answer provided, confirming it as the correct choice. This method of substituting the variable into the expression and evaluating in steps is crucial for solving algebraic expressions accurately.
