Question

Calcule a distância entre os pontos (-2, -1) e (3, -4)

Answer 1

$\large\boxed{\begin{array}{l}\sf d_{A,B}=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\\sf d_{A,B}=\sqrt{(3-[-2])^2+(-4-[-1])^2}\\\sf d_{A,B}=\sqrt{(3+2)^2+(-4+1)^2}\\\sf d_{A,B}=\sqrt{5^2+(-3)^2}\\\sf d_{A,B}=\sqrt{25+9}\\\sf d_{A,B}=\sqrt{34}~u\bullet c\end{array}}$
