Apply the commutative property to 13 x 7 x 21 to rearrange the terms and still get the same solution

13 x 21 x 7

7 x 13 x 21

7 x 21 x 13

21 x 13 x 7

21 x 7 x 13

Step-by-step explanation:

The communicative property basically staters that any way you rewrite a problem, the answer will come out the same.

answer: i'm not sure

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
