Write an integer for situation
5 degrees below 0

-5

Step-by-step explanation:

An integer is a positive or negative number that has no fractions or decimals.

5 degrees above zero is 5 degrees because 0 + 5 = 5

5 degrees below zero is -5 degrees because 0 - 5 = -5

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.
