An aquifer with dimensions of about 325 m in length and 193 m in width is 178 m thick. It has an average porosity of 14%. How many cubic kilometers (km3) of water can the aquifer potentially hold?

0 is its x and y coordinate

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.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
