Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! For sets A and B, determine whether A = B, A is a subset of B, or B is a subset of A
A = {x| x є N and 13 < x < 20}
B = {14, 15, 16, 17, 18}
-----------------------
A = {14,15,16,17,18,19}
B = {14,15,16,17,18}
----------------------
So B is a subset of A since every element in B is an element in A.
-----------
A is not a subset of B because 19 is in A and not in B.
---------------
A is not equal to B because they do not have exactly the
same elements.
