Anugget of gold is placed in a graduated cylinder that contains 85 ml of water. the water level rises to 225 ml after the nugget is added to the cylinder. what is the volume of the gold nugget?

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.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
