Answer:
i think it would be A if not then B
Step-by-step explanation:
Answer:
(x-2)(x+2)(x^2 + 4)
Step-by-step explanation:
This can be done by difference of squares:
(x^2 - 4) (x^2 + 4)
And now (x^2 - 4) can be further factored:
(x-2)(x+2)(x^2 + 4) is your answer
Clearly, There are only 2 zeroes that we can get from this, 2 and -2
Hope this helps!

Answer:
SA = 7.08 in²
Step-by-step explanation:
We can use the following method to solve the given problem
SA = 2B + LA
Where LA
LA = 4.72* 0.05* 15= 3.54
And
C = 2πr
Where
C = 4.72in
π = 3.14
Substituting, we have
4.72 = 2*3.14*r
Making r the subject of formula
r = 0.75in
Solve for the area of CD
A = πr²
Substituting the values we have
A = 3.14 *(0.75)²
A= 1.77 in²
Solving for surface area of the stack
SA = 2(1.77) + 3.54
SA = 7.08 in²
