Question

if A & B r d points(-6,7)&(-1,-5)respectively,then d distance 2AB is equal to??

Answer 1

\[d=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]
2AB
\[d=2\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]

Answer 2

\[d=2\sqrt{(-6-(-1))^{2}+(7-(-5))^{2}}\]\[d=2\sqrt{(-5)^{2}+(12)^{2}}\]\[d=2\sqrt{169}\]\[d=2(13)\]\[d=26\]

Answer 3
