Alisson

In November, Alisson was given $12.

Step-by-step explanation:

The normal amount given to Alisson each month = $x

If in November Alisson was given $9 more than thrice her usual amount of $x, it implies that she was usually given $3 ($9/3) per month because $9 is three times (thrice) than $3.

Therefore, Alisson's usual amount per month which is  $x = $3

This implies that in November she was given $12 ($3 + $9), which was thrice more.

To check the correctness of the above reasoning, we recall that $12 is more by $9 than $3, and $9 is thrice than the $3 given to Alisson per month.

since both sides equal, there are infinitely many olutions.

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.
