PLEASE HELP ody is trying to get stronger and is working on building up the ability to do pushups. She starts off doing 5 pushups and each week increases the number she does by 4. Which of the following equations defines how many pushups will she do in the nth week? (Hint: Try your answer, check it to make sure it works!)
A. an = 4n – 1
B. an = 4n + 5
C. an = 4n + 9
D. an = 4n + 1

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.

126 maybe. sorry
