Question

When x= 5 the value of the expression 20/-25 + x (x - 10) is

Answer 1

The answer is -25.8 because 5-10=-5, -5*5=-25, then you simplify fraction and add/subtract

Answer 2

`(-129)/(5)`

Explanation:

We have been given an expression
`(20)/(-25)+x(x-10)`. We are asked to evaluate our given expression, when
`x=5`.

To evaluate our given expression, we will substitute
`x=5` in our given expression as:

`(20)/(-25)+5(5-10)`

`-(4)/(5)+5(-5)`

`-(4)/(5)-25`

Make a common denominator:

`-(4)/(5)-(5*25)/(5)`

`-(4)/(5)-(125)/(5)`

`(-4-125)/(5)`

`(-129)/(5)`

Therefore, the value of our given expression
`(-129)/(5)`.
