$distance formula: \sqrt{(x _{2}-x _{1})^{2} + (y _{2}-y _{1})^{2}}$when given points (x1, y1) and (x2, y2) so plug in points (-8, 2) and (4 , 7)

2. jigglypuff314

so simplify $\sqrt{(4+ 8)^{2} + (7-2)^{2}}$

ok ty so would it be 235 how do I brake that down please

4. jigglypuff314

mmm try again? :) 4+8 = 12 7-2 = 5 12^2 = 144 5^2 = 25 144 + 25 = 169 square root of 169 = (answer) :)
