12 + 12 = 24
15 + 15 = 30
9 + 9 = 18
3 + 3 = 6
3 + 3 = 6
30 + 20 + 10 = 60
8 + 4 = 12
6 + 6 = 12
60 + 20 = 80
80 + 4 = 84
The area of the figure is 84, I believe.
Part A:
We need to divide
5 ÷ 2/3
5/1 ÷ 2/3
5/1 * 3/2
15/2 or 7 1/2 plates of nachos.
Part B:
If Rachel can make 7 1/2 plates of nachos with 5 cups of cheese we need to multiply and subtract.
ma2/3 * 9 = 18/3 or 6 cups of cheese to make 9 plates
6 - 5 = 1 more cup of cheese she needs to make 9 plates
Best of Luck!

n!/(n-3)!=3.n!/(n-2)!
3. (n-3)!=(n-2)(n-3)!
3=n-2
n=5
