1. use the formula 


2. use the formula

3. There is only one at 360 degrees
4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:
 
        
             
        
        
        
Given:
width of bookshelf no greater than 6 1/2 feet
purchased bookshelf that is 77 inches wide
We need to find the equivalent value in feet of the purchased bookshelf.
1 foot is equal to 12 inches
77 inches * 1 foot/12 inches = 77 ft/12 = 6 5/6 ft
Or we can convert the feet into inches:
6 1/2 feet convert to improper fraction.
((6*2)+1)/2 = 13/2 feet
13/2 ft * 12 inches/1ft = (13 * 12)/2 = 156/2 = 78 inches
Compare the maximum width of 78 inches to the actual width of 77 inches. 
The purchased bookshelf can fit between two windows.  
        
             
        
        
        
In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient. 
In this problem the co-efficient of x = 
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
