Julio is an architect who disigns skyscrapers. assume that each story (also called a "floor" or "layer") of a new building is 15 feet high as you julio answer the following questions: a. how high would two story building be ? what about a ten story? what about a 30 building

Given that each floor is 15 feet high

A . two floors = 15*2 =30 feet high.

B. ten floors =15*10=150 feet high.

C. 30 floors =15*30=450 feet high.

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.
