A renewable resource is a natural resource that can be used repeatedly without running out. They have and unlimited supply. (ex. solar power)

A nonrenewable resource is a natural resource that will run out and can not be reused. (ex. coal)

Weathering is the breaking down of rocks and minerals through contact with Earth's natural forces.

Erosion is when the forces of the earth breaks down rocks and minerals and moves them to another place.

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.

if you need just tell me and i will come to the rescue.
