To solve this problem you must apply the proccedure shown below:
1. You have that:
- T<span>he equation d=1/2(n(n-3)) gives the number of diagonals for the polygon.
- The polygon that has 65 diagonals..
2. When you clear n, you obtain:
d=n(n-3)/2
d=(n^2-3n)/2
2x65=n^2-3n
n^2-3n-130=0
3. When you solve the quadratic equation, you obtain:
n=13
Therefore, the answer is: 13 sides. </span>
Answer: Area = 5
Step-by-step explanation:
First you would multiply 3/4 by 2 then multiply 1/2 by 4 and get 6/8 and 4/8.
Yes 4/5 is greater than 1/3. Convert the fractions to the same denominator so 1/3 becomes 5/15 and 4/5 becomes 12/15. So 12/15 is more than 5/15.
