If A is a subset of B, then all elements from a set A are in a set B.
The number 8 from {3, 8, 6} is not in the set {1, 2, 3, 4, 5, 6}. Therefore {3, 8, 6} is not a subset of {1, 2, 3, 4, 5, 6}.

Crystal has 121 compact discs. The total number of boxes required are 5.
<u>Solution:</u>
Given, Crystal has 121 compact discs that she wants to put into boxes.
Each of the boxes that she brought home holds 25 discs.
We have to find how many of these boxes will she need for all of her discs?
Now, we know that, number of boxes required 
Here we took 5 because 0.84 means that box with discs less than 25 still we require a box.
Hence, the total number of boxes required are 5.

Answer:
20 m
Step-by-step explanation:
The width is half the length, and the perimeter is the sum of the lengths of all sides. We can write the equation of the perimeter as ...
... 60 m = L + L/2 + L + L/2
... 60 m = 3L . . . . . collect terms
... 20 m = L . . . . . . divide by 3
