Brad and Barb are trying to find the length of a line segment connecting two points, (x1, y1) and (x2, y2). Brad uses the formula

d =
(x2 - x1)2 + (y2 - y1)2
.

Barb uses a different formula, but still gets the right answer. Which formula COULD she have used?

Because the numbers are going to be squared the order doesn't matter so the answer would be 
[tex] \sqrt{(x1-x2) ^{2} + (y1-y2)^2 } [/tex]

Answer: √ (x1 - x2)2 + (y1 - y2)2

Step-by-step explanation: √  (x1 - x2)^2 + (y1 - y2)^2  is correct. Since the two binomials are being squared, the order of the terms does not matter.
