You would take out a 4x out of both terms because this is a common factor
4x^3-36x
4x(x^2-9)
and then you would notice that (x^2-9) is a difference of squares, so that factors out too
4x(x-3)(x+3)
that is all you can factor! hope this helps
Answer:
Amount of fresh water = 3.5 * 10^7 cubic kilometers
Step-by-step explanation:
Given the following
Total water on earth = 1.4×10^9 cubic kilometers
If 2.5% of it is fresh water
Amount of fresh water = 2.5% of 1.4×10^9
Amount of fresh water = 0.025 * 1.4×10^9
Amount of fresh water = 0.035 * 10^9
Amount of fresh water = 3.5 * 10^7 cubic kilometers
