4 $sqrt(2)$

If d is the distance between two points (43, -13) and (47, -17)

We know $d$ = $sqrt((x_2 -x_1)^2+(y_2-y_1)^2)$

= $sqrt((47 -43)^2+(-17-(-13))^2)$

= $sqrt((4)^2+(-4)^2)$

= $sqrt(16+16)$

= $sqrt(32)$

= $sqrt(2X4^2)$

= 4 $sqrt(2)$

What is the distance between (43,-13)(43,-13) and (47,-17)(47,-17)?
