Combinatorial Enumeration. That whole class was a rollercoaster ride of mind-blowing generating functions to prove crazy things. The exam had ridiculous questions like 'count the number of cactus trees with n vertices such that etc etc etc' and you'd do three pages of terrible terrible sums and algebra.

The coefficient 7 means that the length is 7 times the width
<h3>How to interpret the coefficient?</h3>

Length = 7x
Substitute Width = x in Length = 7x
Length = 7 * Width
This means that the length is 7 times the width
