I think its 6 but im not sure
Since she has 57 cans and 3 cans are allready devoted to the last row u must do 57-3 in or to get 54 cans total leftover. Then divide the number 54 by 9 since there are nine rows.so i think there will be six cans on each row of the shelf!
Step-by-step explanation:
A={3,4,7,9}
B={8,9,10,11}
now,
AUB={3,4,7,9}U{8,9,10,11}
={3,4,7,8,9,10,11}
hope it helps.
A. y = (2x)^2
Replace x and y with your point
16= (2•2)^2
16= (4)^2
16= 16
