por favor ,,,,,,por favor ..... por favorrrr .... gente me ajudemmm

Answer 1

As questões pedem para calcular distância:

$A(2;-3);B(4;5)\\\\\\ D_{AB}= \sqrt{(x_b-x_a)^2+(y_b-y_a)^2} \to \\\\\\ D_{AB}= \sqrt{(4-2)^2+(5-(-3))^2} \to \\ \\D_{AB}= \sqrt{(4-2)^2+(5+3)^2} \to \\\\ D_{AB}= \sqrt{(2)^2+(8)^2} \to \\\\ D_{AB}= \sqrt{4+64} \to \\\\ D_{AB}= \sqrt{68} \to \\\\ D_{AB}= \sqrt{2^2*17} \to \\\\D_{AB}= 2\sqrt{17}$







$P(-2;3);Q(-5;-9)\\\\\\D_{AB}= \sqrt{(x_b-x_a)^2+(y_b-y_a)^2} \to \\\\\\ D_{AB}= \sqrt{(-5-(-2))^2+(-9-3)^2} \to \\\\D_{AB}= \sqrt{(-5-(-2))^2+(-9-3)^2} \to \\\\ D_{AB}= \sqrt{(-5+2)^2+(-9-3)^2} \to \\\\ D_{AB}= \sqrt{(-3)^2+(-12)^2} \to \\\\ D_{AB}= \sqrt{9+144} \to \\\\ D_{AB}= \sqrt{153} \to \\\\ D_{AB}= \sqrt{3^2*17} \to\\\\ D_{AB}= 3 \sqrt{17}$
