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

The correct answer is option A.

Step-by-step explanation:

The associative property of addition states that during addition, you can group the numbers in any combinations. This grouping in any way will produce the same results. This property can be shown as :

So, the answer here will be :

A. (-4 + i) + 4i = -4 + (i + 4i)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
