When you divide two fractions, you actually just flip one over (it's reciprocal) and multiply them.

Use the recriprocal of

Now, check the picture below
the area of the cross-sections, is really the same area as the rectangular faces, so, just use those areas, since they're the same
Answer:
First choice A : 2x +3y is <em>less than or equal </em><em>to</em><em> </em>18. x <em>greater</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em>0. y <em>greater</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em>0.
It simplifies to -6a^6b^2c^5+2a^2bc^6
You have the following equation:

In order to solve the previous equation for y, proceed as follow:
3 + y/2 = -212 subtract 3 both sides
y/2 = -212 - 3 simplify right side
y/2 = -215 multiply by 2 both sides to cancel the denominator left side
y = -215(2)
y = -430
Hence, the solution for y in the given equation is y = -430
