Answer:
a) 1. Equivalent expression
b) 3. (wx)yz
c) 2. wx(yz)
Step-by-step explanation:
1. According to the associative property, the result of the addition or the multiplication of three or more numbers are the same irrespective of the order of the grouping of the numbers.
(a + b) + c = a + (b + c)
That is the result of the equation is not affected by the rearrangement of the parenthesis to group the numbers
In the given question
w(xy)z = (wx)yz
w(xy)z = wx(yz).
6x6 = 36
1/2(6)(6) = 18
1/2(6)(6) = 18
36+18+18 = 72
answer is D. 72 in^2
