Tamara need tiles to make a border for her bathroom wall. the border will be 9 feet long and 1/3 foot wide. each tile measures 1/3 foot by 1/3 foot. each box of tiles contains 6 tiles. how many boxes of tiles doe tamara need? write two equations that can be used to solve the problem.

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.

stops on an even number.
