Answer:
71 degrees
Step-by-step explanation:
A right angle is 90 degrees, so the answer is 90-19=71 degrees.
The rule to convert a mixed fraction to an improper fraction is

Here in 
Here a = 422, b = 8 and c = 100
Now a × c = 422 × 100 = 42200
And 42200 + 8 = 42208
So we have

This fraction can also be reduced as

Hence

Fisrst one is just add the functions
(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3
multiply
ok
f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now
