5 : 22.17. A flagpole is n feet tall. On this pole we display flags of the following types: red flags that are 1 foot tall, blue flags that are 2 feet tall, and green flags that are 2 feet tall. The sum of the heights of the flags is exactly n feet. Prove that there are 2 3 2 n C 1 3 .1/n ways to disp

Prove attached below

Step-by-step explanation:

Attached below is the detailed solution to prove that there are

flagpole length = n feet

number of flags = 3

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
