Question

qual a distancia entre dois pontos c (-3, 5) e (-3, 12)

Answer 1

$C~(-3~;~5)~~~e~~~E~(-3~;~12)\\\\\\ D_{ce}= \sqrt{(x_b-x_a)^2+(y_b-y_a)^2} \\\\\\ D_{ce}= \sqrt{(-3-(-3))^2+(12-5)^2}\to \\\\ D_{ce}= \sqrt{(-3+3)^2+(12-5)^2}\to \\\\ D_{ce}= \sqrt{(0)^2+(7)^2}\to \\\\ D_{ce}= \sqrt{49}\to \\\\ \large\boxed{D_{ce}=7}$
