Answer:

2x^2 + 4x+2

Step-by-step explanation:

f(x) = 2x^2 + x and g(x) = 3x + 2

f(x) + g(x) =  2x^2 + x + 3x + 2

            Combine like terms

               = 2x^2 + 4x+2

Answer:

f(x)+g(x)=2x^2+4x+2

Step-by-step explanation:

So we have the two functions:

f(x)=2x^2+x\text{ and } g(x)=3x+2

And we want to find:

f(x)+g(x)

So, substitute:

=(2x^2+x)+(3x+2)

Combine like terms:

=2x^2+(x+3x)+2

Add:

=2x^2+4x+2

So:

f(x)+g(x)=2x^2+4x+2

And we're done!

WARRIOR [948]

Answer:

-6=7 NO SOLUTION

Step-by-step explanation:

First, distribute the -3 to the (k +2)

Your equation becomes, -3k-6=-3k+7

Add 3k to both sides to have the variables be on the same side

Your equation becomes, -6=7

Since that isn’t true, it’s a no solution

I hope this helps!
