What are all the zeros of the function g(x)=

Firstly, set g(x) to zero:

So for this, we will be factoring this function using the difference of squares. The difference of squares is . Using our function, apply this as such:

Next, we are going to apply the Zero Product Property, which states that "if a × b = 0, then either a or b = 0 or both a and b = 0." In this case, a = x + 5 and b = x - 5. Solve each for zero:

The zeros of this function are 5 and -5. The correct option is C.

step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
