Question

the distance between the point (3,4)and (8,-6)_______​

Answer 1

Answer:

Step-by-step explanation:

D= $\sqrt{(x_{2}-x_{1 })^{2} + {(y_{2}-y_{1 })^{2 }$

$x_{1} = 3, x_{2}=8 , y_{1 }=4,y_{2 }=-6\\D=\sqrt{(8-3)^{2}+(-6-4)^2 }$

$D=\sqrt{5^{2}-10^2 } \\\\ =\sqrt{25-100} \\ \\ = \sqrt{75}\\ \\ =5\sqrt{3}$
