If x = 3, what is the value of 2x + 5?

If x = 3, what is the value of 2x + 5?

• A. 7
• B. 8
• C. 11
• D. 15

Answer: (C)

To find the value of the expression \(2x + 5\) when \(x = 3\), you first need to substitute 3 for \(x\) in the expression. The expression then becomes: \[ 2(3) + 5 \] Next, you calculate \(2(3)\), which equals 6. So now the expression is: \[ 6 + 5 \] When you add 6 and 5 together, you get 11. Thus, the value of the expression \(2x + 5\) when \(x = 3\) is 11, which corresponds to the correct answer.

To find the value of the expression (2x + 5) when (x = 3), you first need to substitute 3 for (x) in the expression.

The expression then becomes:

[

2(3) + 5

]

Next, you calculate (2(3)), which equals 6. So now the expression is:

[

6 + 5

]

When you add 6 and 5 together, you get 11.

Thus, the value of the expression (2x + 5) when (x = 3) is 11, which corresponds to the correct answer.
