(f+g)(x)=-2x+6
(f-g)(x)=8x-2
(f*g)(x)=-15x^2+2x+8
(f/g)(x)=3x+2/4-5x
Answer: 254.34
Step-by-step explanation:
The area of a circle is calculated by the formula A=π r²
A = Area
r² = radius squared
Putting the numbers into the formula:
A = 3.14 x 9²
A = 3.14 x 81
A = 254.34
X2+12x+11=0
x2+12x+(12/2)^2-(12/2)^2+11=0
(x+6)^2-36+11=0
(x+6)^2=25
(x+6)=+-5
x= +5-6 or -5-6
= -1 or- 11
