Mr. marquis had a metal pipe that was 1,000 cm in length. he cut the pipe into 16 shorter pieces of equal length. how long was each piece?

To answer this, divide 1000 cm by 16:

1000 cm

= 66 2/3 cm per piece

  16 pieces

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.
