An engineer tests the strength of a new material by seeing how much weight it can hold before breaking. Previous tests have held these weights in pounds: 1,200 1,400 1,300 1,500 950 1,600 1,100 Do you think that this material will be able to hold more than 1,000 pounds in the next test? Explain your reasoning. *

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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.
