Answer:
9x^2+4x+5
Step-by-step explanation:
f ( x ) = 5x^2 - 2x + 6
g ( x ) = 4x^2 + 6x - 1,
Add the functions together
f(x)+ g(x) = 5x^2 - 2x + 6 + 4x^2 + 6x - 1
Combine like terms
=9x^2+4x+5
In order to isolate k, we would first cross multiply
3*k=9*10
3k=90
Then to isolate k, we would divide both sides by 3 to get:
K=30
Hope this helps
