Answer 2

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{4}~,~\stackrel{y_1}{5})\qquad B(\stackrel{x_2}{1}~,~\stackrel{y_2}{2})\qquad \qquad % distance value d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ AB=√((1-4)^2+(2-5)^2)\implies AB=√((-3)^2+(-3)^2) \\\\\\ AB=√(9+9)\implies \boxed{AB=√(18)}\implies AB=√(2(9)) \\\\\\ AB=√(2(3^2))\implies \implies AB=3√(2)`
