Question

Si A(2; 5); B(5; 9) y C(–7; 4).Calcule d(AB) + d(BC).

Answer 1

Respuesta:

18

Explicación paso a paso:

$d(AB)=\sqrt{(5-2)^{2}+(9-5)^{2}} ----- d(BC) = \sqrt{(-7-5)^{2}+(4-9)^{2}} \\d(AB) = \sqrt{9+16} ----------- d(BC) = \sqrt{144+25}\\d(AB) = 5 --------------d(BC) = 13\\RPTA : 5+13 = 18$
