6) The area of a regular OCTAGON is 100 centimeters squared. To the nearest TENTH of a centimeter, what is the apothem if the side length is
4.4 cm?

I am filling in this answer for now as a holding spot and I will answer this later when I get the chance!

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
