Answer
$A\subseteq B$
$A\subset B$
Work Step by Step
Written using the roster method, the sets are equal to:
$A=\{6, 7, 8, 9, 10, 11\}$
$B=\{4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16\}$
We can see that.
$A\subseteq B$ is true, as every element in set $A$ is also an element in set $B$,
$A\subset B$ is true, as $A\subseteq B$ and A and B are not equal.
