<span>Answer: option B. She did not set the width of the compass to the radius of the circle.
Explanation:
1) If she sets the compass to an arbitrary width to </span><span>draw the arc to cut the circle, the point obtained will not be to the right distance from the first vertex.
2) All the adjacent vertices on a regular polygon have the same distance one from each other.
3) In the hexagon that distance is the same radius, which you can see becasue you can form six equilateral triangles inside the circle, whose side lengths are the radius.
4) So, she should set the width of the compass to the radius of the circle.

Answer:
Option (2).
Step-by-step explanation:
The given expression is [
]
We can rewrite the fractions as,
= 

Now we will substitute the fractions in the expression,
![[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]](https://tex.z-dn.net/?f=%5B-%285%2B%5Cfrac%7B1%7D%7B4%7D%29%5D-%5B-%287%2B%5Cfrac%7B1%7D%7B2%7D%29%5D)
= 
= (-5 + 7) + 
= 2 + 
= 2 + 
= 
Therefore, Option (2). will be the answer.
