Best ResponseYou've already chosen the best response.0\[\sqrt{(y2y1)^2+(x2x1)}\] This is the formula we use to find the distance between points. So if we pluck (1,3) & (5,0) in this formula we have \[\sqrt{(15)^2+(30)^2}\] Then we do what are in bose parenthesis and get \[\sqrt{(6)^2+(3)^2}\] Once we put the exponents & add it together we now have \[\sqrt{45}\]

Best ResponseYou've already chosen the best response.0dw:1347663557537:dw If we have to simplify \[\sqrt{45}\] we list all the factors of 45. 45=5*3*3. When there's two of a number we can cancel that out and put it on the other side of the square root. That means we then get \[3\sqrt{5}\]
