The height of the kangaroo is 4 feet and it's shadow is 9 feet. The relationship between the kangaroo and its shadow is 4/9. This has to be equal to that of the eucalyptus tree. The relationship of the eucalyptus tree is x/36.
4/9=x/36

You can either solve for x by realizing that in order to get from 9 to 36, you multiply by 4 and therefore have to multiply 4 by 4 to get x.
Or you can solve for x by cross multiplication. 36(4)=144. You then divide 144 by 9.

Either way, x = 16 and the height of the tree is 16 feet.

2x+9<0
This is asking for numbers below 0
x>-12
This is asking for numbers above - 12

So the numbers which would fit in both of these rules would be:
-11, -10, -9, -8, -7, -6, -5

Any numbers above or below these wouldn't fit into any of the inequalities

First find the volume of the pool. To do so, multiply the length, times the width, times the height. In this case, it would be 12*15*5 and you get 900 cubic meters.
If the pool is being filled with 36 cubic meters of water per hour, you divide 900 by 36. You get 25 hours.
To check your work, multiply 25 hours and 36 cubic meters of water. You get 900 cubic meters, which is the area of the pool meaning it is full.
