Question

Find the distance the points (-3,-5) and (9,-10). Enter the exact value of the answer.

Answer 1

`\begin{gathered} \text{ the distance between the points is} \\ d((-3,-5),(9,-10))=\sqrt[]{(-3-9)^2+(-5-(-10))^2} \\ =\sqrt[]{(-12)^2+5^2} \\ =\sqrt[]{144+25} \\ =\sqrt[]{169} \\ =13 \\ \\ \text{ The distance is 13} \end{gathered}`
