Commutative property means that you can rewrite the equation in a different order. So for example, if I have 3 + 8 + 5 I can rewrite it as 5 + 3 + 8 or 8 + 5 + 3 and so on and so forth. So, we must go over all the options to narrow it down. It isn't B or C, So lets look at D. D shows you 12 + 6 + 15 = 12 + 6 + 15 this is the wrong answer because it does not rewrite the equation. It just repeats itself so lets take a look at option A. A says 12 + 6 + 15 = 12 + 15 + 6 this is the correct answer because it rewrote the equation in a different order but they are still the same numbers.
So the correct answer is
A) 12 + 6 + 15 = 12 + 15 + 6

Answer:

Step-by-step explanation:

Use the distance formula for coordinate geoemetry and the fact that x1 = 3, y1 = 5, x2 = 6 and y2 = 8 to fill in the formula:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$
