6 cups

Step-by-step explanation:

54 ÷ 9 = 6

1 cup for every 9 MS

2 cups/ 18 MS

3 cups/ 27 MS

4 cups/36 MS

5 cups/ 45 MS

6 cups/ 54 MS

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.
