Answer:
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.
The Commutative property states that order does not matter. Multiplication and addition are commutative.

Answer:
420 inches or 35 feet of trim is needed for 5 desks.
Step-by-step explanation:
We know that one desk requires 84 inches, so we need to find out how many inches are needed for 5 desk.
If we know one desk needs 84 inches then we have 1 desk = 84 inches.
To get 5 desk, we need to multiply both sides by 5.
1 desk = 84 inches. (multiply by 5 for both sides)
5 desks = 84 * 5
5 desks = 420 inches
We know now that 5 desks require 420 inches, but many people use feet instead.
There are 12 inches in 1 foot, so we need to divide 420 inches by 12 inches to get how many feet we need.
420/12 = 35 feet.
Hope this helps!
