Answer:
32
Step-by-step explanation:
XY means x times y 
and x = 8 or x is 8
and y = 4 or y is 4
so 4 times 8 is 32
so 
XY = 32
 
        
             
        
        
        
28457 x 3 = 85371 white blankets
85371 + 28457 = 113,828 total blankets
113828/55 = 2069.6 total boxes
so 2069 full boxes
and 55*.6 = 33 left over blankets
 
        
             
        
        
        
18xy
You need to do 6*3=18
Then x*y= xy 
        
             
        
        
        
So you would find out what number in the 9 times tables goes into 25 and there's your answer x
        
             
        
        
        
Two composite numbers that have 8 as a factor are 16 and 24.
