In converting 4.5 pounds to ounces, what unit (omit the number) would you place in the numerator of your ratio? Use the plural form in your answer.
Remember that there are 16 ounces in 1 pound.

72 ounces

Step-by-step explanation:

4.5×16

=72

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.
