Answers: 2
![\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{-4}~,~\stackrel{y_1}{2})\qquad B(\stackrel{x_2}{12}~,~\stackrel{y_2}{4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ AB=\sqrt{[12-(-14)]^2+[4-2]^2}\implies AB=\sqrt{(12+14)^2+(4-2)^2} \\\\\\ AB=\sqrt{26^2+2^2}\implies AB=\sqrt{680}](/tpl/images/0068/9086/137db.png)
