Question

What is the value of the rational expression 2x+1 : x*2 when x=5?

Answer 1

The correct answer is third option

11/25

Explanation:

It is given an expression (2x + 1)/x²

To find the value of x

We have (2x + 1)/x²

When x = 5, substitute the value of x in expression we get,

(2x + 1)/x² = (2 * 5 + 1)/5²

= (10 + 1)/25

= 11/25

The correct answer is third option

11/25

Answer 2

The correct answer option is
`\frac { 1 1 } { 2 5 }`.

Explanation:

We are given the following rational expression and we are to evaluate and find its value when x is equal to 5 (
`x = 5`:

`\frac { 2 x + 1 } { x ^ 2 }`

So substituting the given value of
`x` to find the value of the given rational expression:

`\frac { 2 (5) + 1 } { 5 ^ 2 }` =
`\frac { 1 1 } { 2 5 }`
