Answer:
None of the above. 
Step-by-step explanation:Yes, all of the sides match, which would make it an equilateral polygon. However, it is not an equiangular polygon because not all of the angels are the same. In this case, since the angles do not mach and only the sides do, this is not a regular polygon. This is what leads me to believe that is none of them. All of the sides must be congruent and all interior angles must also be congruent. 
 
        
             
        
        
        
1 lb / 0.45 = 2.22
 so approximately 2.22 kilograms per pound
 divide price per pound by kilometers per pound
1.44 / 2.22 = 0.648
 round to 0.65, so it costs $0.65 per kilogram

Answer:
Step-by-step explanation:
On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs. 
After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.
Therefore we can write the following equation:  (Where d = number of days)
B = 10 + 8d 
W = 0 + 9d = 9d 
We are told that eventually they will sell the same amount which means 
B = W
This means we can say, 
10 + 8d = 9d 
If we subtract 8d from both sides we get 
10 = d 
Therefore it will take 10 days for them to sell the same amount of cookie dough.
