Answer:
The polynomial that represent the volume of the box is 
Step-by-step explanation:
we know that
The volume of the box is equal to

we have



substitute in the formula

Step-by-step explanation:
(f+g)(x) means we just add the 2 functions, so we have
(x-3) + 2x² = 2x² + x - 3
(f-g)(x) means we subtract g(x) from f(x), so we have
(x-3) - (2x²) = -2x²+x-3
Assuming that the dot signifies a multiplication sign and not a composition sign, we have
(f*g)(x) = f(x) * g(x)
= (x-3) * 2x²
= 2x³ - 6x²
Plugging -2 in, we get
2(-2)³-6(-2)² = -16 -24 = -40
After a thorough research, there exists the same question that has the following choices.
A. 6.29
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>
The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57
