The value ( in credis) of a piece of jade varies directly as the cube of its volume ( in cm^3). If the value of a piece of jade of volume 2cm^3 is 6720 cedis, find the value of a piece of jade of volume 3.5 cm^3. If the piece of jade of volume 2cm^3 is broken into two parts of equal volume, what would be the percentage loss in its value?

the answer to this question is in the pic

the answer is 62

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.
