F(x)=3x+5/x, what is f(a+2)

A+2

Step-by-step explanation:

Given a defined function  

f

(

x

)

, we can evaluate the function at any constant by replacing every  

x

with that constant.

So if  

f

(

x

)

=

3

x

+

5

x

, then  

f

(

a

+

2

)

=

3

(

a

+

2

)

+

5

a

+

2

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
