Lena is a software saleswoman. her base salary is $ 1800 , and she makes an additional $ 120 for every copy of english is fun she sells. let p represent her total pay (in dollars), and let n represent the number of copies of english is fun she sells. write an equation relating p to n . then use this equation to find her total pay if she sells 27 copies of english is fun.

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.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

i think the answer is true
