If f(x)=3x+10x and g(x)=4x-2 find (f+g)(x)
a: 3x+6x+2
b: 17x-2
c: 3x+14x-2
d: 3x-6x+2

3x^2+14x-2 if you meant f(x)=3x^2+10x and g(x)=4x-2

and I think C was meant to read 3x^2+14x-2

Please correct me if I have mistranslated. Thank you kindly.

Step-by-step explanation:

I kind of wonder if you meant f(x)=3x^2+10x and g(x)=4x-2.

(f+g)(x)=f(x)+g(x)

          =(3x^2+10x)+(4x-2)

          =3x^2+10x+4x-2

          =3x^2+(10x+4x)-2  I paired 10x and 4x together because    they are like terms

         =3x^2+14x-2
