To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))

Answer:
1000 m³
Step-by-step explanation:
The base of a cube is just a square.
The area of a square is
, where l is the length.
Since we know the area of the base (the square) we can find l easily.

Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.
This means the height of the cube is also 10m.
Since the volume of a cube is represented as
, where l is the length, we can substitute 10 in as
to find it's total volume.

So the volume of this cube is 1000 m³.
Hope this helped!

Answer:
$9486.68
Step-by-step explanation:
The future value of a annuity formula can be used:
FV = P((1+r)^n -1)/r
750000 = P(1.06^30 -1)/0.06
P = 750000(.06)/(1.06^30 -1) = 9486.68
