The associative property is basically just when you move the parentheses in a problem. For example: (a+b)+c = a+(b+c).
Distributive property is a little more complicated, its better if i show you.
a(b+c) = ab+ac
so a times b plus c is the same as a times b plus a times c.
Hope i helped:)

Answer:
24 yd
Step-by-step explanation:
Treat x as the desired quantity. This x is the side of the triangle adjacent to the lower 12 degree angle. The side opposite this angle is 5 yds. Using the definition of the tangent,
tan 12 degrees = opp / adj = 5 yds / x
Then x = (5 yds) / (tan 12 degrees), or x = (5 yds) / 0.213
Then x = 24 yds (to the nearest yd)
Answer: 
Step-by-step explanation:
The first thing you must remember is the mulplication of signs. You know that:

You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:

Now, you need to add these numbers. And the result obtained is:
