Question

If f(x)=2x+5x and g(x)=3x-5,find (f+g)(x)

Answer 1

`10x-5`

Explanation:

`f(x)=2x+5x`

`g(x)=3x-5`

`(f+g)(x)`

`f(x)+g(x)`

`2x+5x+3x-5`

`10x-5`

Answer 2

The answer is
`(f+g)(x)=10x-5`

Explanation:

Given that
`f(x)=2x+5x` and
`g(x)=3x-5`

To find :
`(f+g)(x)`

Now, assign the value
`g(x)=3x-5` in
`(f+g)(x)`

`(f+g)(x)=(f+3x-5)`

Also, assign the value
`f(x)=2x+5x` in
`(f+g)(x)`

`(f+g)(x)=(2x+5x+3x-5)`

Now, adding the like terms , we get,

`(f+g)(x)=10x-5`

Thus, the value of
`(f+g)(x)` is
`(f+g)(x)=10x-5`
