Due tomarrow ! identify the independent and dependent variables in the following statement. the more water flowing into the pool, the greater the water depth is in the pool. a. the independent variable is the depth of water in the pool, and the dependent variable is the rate that water is flowing into the pool. b. the independent variable is the rate that water is flowing into the pool, and the dependent variable is the depth of water in the pool.

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.
