Question

What is the value of the rational expression2x+1when x = 5?

Answer 1

We are given the following expression:

`2x+1`

We are asked to determine the value of the expression when x = 5. To do that we will replace the value of "x" in the expression for 5:

`2(5)+1`

Solving the operations:

`10+1=11`

Therefore, the value of the expression when x = 5 is 11.
