Answer:
the answer should be 360/36=10 sides
Step-by-step explanation:
A regular polygon is 144 deg the exterior angle is 36 deg.
First we calculate how many ways you can choose four books from a set of eight.
We use the formula n! / [r! * (n-r)!]
8! / [4! * 4!]
= 8*7*6*5 / 4*3*2*1 = 70 ways
Then we have to calculate how many permutations can be made from 4 objects which equals 4*3*2*1 = 24
So, the TOTAL number of ways = 70 * 24 = 1,680
The answer is 12.50 and equation is y=5.25p -3.25
Answer:
y=x-2
Step-by-step explanation:
if x: 5, x-2=3
y=x-2
therefore:
y=3
x=5
