Answer:
4x^2 -8
Step-by-step explanation:
f(x)=3x^2-9
g(x)=x^2+1
(f+g)(x)=3x^2-9 +x^2+1
Combine like terms
= 4x^2 -8
The formula for the area of a trapezoid is a=1/2(b1+b2)h
So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100
the straight line will always equal 180 degrees.
180-125-35=20
the answer for the missing degree is 20
a. y = -x² + 2x - 8
b. y =
c. y = x³+ 3
