What is the value of the expression 2x + 3 when x is 5?

To find the value of the expression (2x + 3) when (x) is (5), you will substitute (5) into the expression where (x) is located.

Start by replacing (x) with (5):

[

2(5) + 3

]

Calculating (2(5)) yields (10). Next, you add (3) to this result:

[

10 + 3 = 13

]

Thus, the value of the expression (2x + 3) when (x) is (5) is (13). This reasoning confirms that the correct answer is (13).

The other choices, (10), (15), and (16), do not align with the calculations and therefore do not represent the correct evaluation of the expression given the value of (x).
