Question

What is the distance between points (12, 4) and (18, –1)? Round to the nearest tenth.

Answer 1

7.8`

Answer 2

\[d=\sqrt{_{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}}\]
\[d=\sqrt{(18-12)^{2}+(-1-4)^{2}}\]
\[d=\sqrt{36+25}=\sqrt{61}\]
\[d \approx7.8\]

Answer 3

omg thank you soooo verry much for the help (:
