If this is just estimating, then the answer 2 miles in total would be sufficient. to be exact, Ron walked 17/10 miles/ 1 and 7/10 miles.
Answer:
(60 x 25) - 25 = 1475
Step-by-step explanation:
The answer to this question is D
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>
