The question requires us to add the two functions. 
F(x)=8−4x−x³
g(x)=x²<span>+7x−9

</span>F(x)+g(x) = (8−4x−x³)+(x²+7x−9)
                =8-9+7x-4x+x²-x³
                = -1+3x+x²-x³

                =x²-x³+3x-1

I don’t understand, please help! Solve m=p/2-n for n.
belka [17]

Answer:    n=p/2-m

Step-by-step explanation:

m=p/2-n   (1)

Add n to both sides of the equation  (1)

m+n=p/2-n+n => m+n=p/2     (2)

Subtract m from both sides of the equation (2)

m-m+n=p/2-m => n=p/2-m
