I need help please.

A: 4

B: it means that they have an absolute value of 4 levels between them.

C: 3+4

D: It will be greater than the value of a because you are adding onto it. If a is negative and b is positive thne it will be less than since you are subtracting a positive from a negative number

Step-by-step explanation:

Let me know if you need more in-depth on HOW to do it.

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.
