Simplify the expression

14.9x + 1/3(-12-27x) - 33.2

where x= -3

10

step-by-step explanation:

7+3=10

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.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
