Answer:
mean: 13
range: 15
there is no mode 
median: 13.5
Step-by-step explanation:
mean= 14+9+20+5+17+13 = 78
78÷6= 13
range = highest number minus the smallest number 
20-5 = 15
the mode is the number that occurs the most 
median= 13+14= 27
27÷2 = 13.5
 
        
             
        
        
        
(w³+7)/w=(9w²+7)/9
(w³+7)9=(9w²+7)x
9w³+63=9w³+7x
63=7x
x=9
