Question

ind the distance between
A(-5,7), B(-2,4)​

Answer 1

$\huge{\mathfrak{\blue{\underline{Answer}}}}$

Distance formula :

$= \sqrt{(x _{2} - x _{1}) {}^{2} +(y _{2} - y _{1} ) {}^{2} } \\ = \sqrt{ (- 2 - ( - 5)) {}^{2} + (4 - 7) {}^{2} } \\ = \sqrt{( - 2 + 5) {}^{2} + (4 - 7) {}^{2} } \\ = \sqrt{(3) {}^{2} + ( - 3) {}^{2} } \\ = \sqrt{9 + 9} \\ = \sqrt{ 18}$

The distance is √18 units
