Step-by-step explanation:

In this figure, |v| represents the absolute value to 0. For example, |-3| would be 3 because it is 3 spaces from 0.

|10| - 3 × |-2| +5

10 - 3 * 2 + 5

10 - 6 + 5 ^ PEMDAS

-4 + 5

the correct answer is the second option

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.
