Question 744948: So I have determined that by using Leonhard Euler's formula for polygon division
T(6) = 14
T(7) = 42 and
T(8) = 132
however I am confused about how T(n) changes when you ignore distinct vertices.
Could you explain how to find T(n) while ignoring said vertices.
Note: I'm not looking for the answer but rather an explanation on how to reach the answer.
Thanks!

Question 752341: a standard sign is a rectangle with measurement 36 in. by 12 in. The sheet metal they're to be made of measures 60 in. by 90 in. What is the maximum number of signs that can be made from the sheet metal.
I tried dividing the area of the signs (432 in. ) into the area of the sheet metal (5,400), and I get 12 with some leftover material. The question is multiple choice, though, and 12 is not an option. Only 5, 8, 9, and 10.
