What law is applied
The applied law is commutative law of addition.
This law states that:

So:

When the positions of 2 and b are interchanged, we have:

Remove bracket

No, you cannot use the Associative properties with either subtraction and division, because it will not end to the same result. 14-8 is not the same as 8-14, and 24/4 is not the same as 4/24, but for example 3+2 is the same as 2+3.
Answer:
a. (5,4)
b. s
Step-by-step explanation:
use SOHCAHTOA
S = sine
O = opposite edge
H = hypotenuse
T = Tangent
A = adjacent edge
C = cosine.
The extreme is where the runaway is indicated by the hypotenuse is the required distance. Therefore,
sine 7= 3/H
H = 3/sine 7= 24mi
