To find the value of the expression 2(x + 3) when x = 2, you first substitute 2 into the expression for x.

Starting with the expression:

[

2(x + 3)

]

you replace x with 2:

[

2(2 + 3)

]

Next, simplify the expression inside the parentheses:

[

2 + 3 = 5

]

Now you have:

[

2(5)

]

Then, multiply:

[

2 \times 5 = 10

]

Thus, the value of the expression 2(x + 3) when x = 2 is 10. This matches the answer listed, which indicates that the calculation is correct, leading to the conclusion that 10 is indeed the final value derived from the expression.
