Which equation shows an example of the associative property of addition?

(-7 + 1) + 71 = - 7 + (i + 78)

(-7 + 1) + 7i = 71 + (-7i+1)

71% (-77 + 1) = (71-71) + (7ix)

(-71 + 1) + 0 = (-71 + 1)

D

(-71+1) + 0 = (-71+1)

This is because the whole equation involves addition thus it is an example of associative property of addition

(-71 + 1) + 0 = (-71 + 1)

Step-by-step explanation:

Given 3 numbers: a, b, c

Associative property of addition: (a + b) + c = a + (b + c)

On this case: a = - 71

b = 1

c = 0

(a + b) + c = (-71 + 1) + 0 = - 70 + 0 = - 70

(-71 + (1 + 0)) = (-71 + 1) = - 70

Both the sums are equal to - 70 and hence the associative property of addition for the three numbers a = - 71, b = 1, c = 0 holds.

All the other options in the question contain a reference to variable i and does not have the same three values a, b, c on both sides of the equality. So they do not represent the associative property.
