Question

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

Answer 1

Answer:

$10x-5$

Step-by-step 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 $(f+g)(x)=10x-5$

Step-by-step 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 $(f+g)(x)=10x-5$
