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

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.
