Question

Calcule a distância entre os pontos:

W(-4,4) e Z(3,4)​

Answer 1

Explicação passo-a-passo:

$\sf d=\sqrt{(x_Z-x_W)^2+(y_Z-y_W)^2}$

$\sf d=\sqrt{(-4-3)^2+(4-4)^2}$

$\sf d=\sqrt{(-7)^2+0^2}$

$\sf d=\sqrt{49+0}$

$\sf d=\sqrt{49}$

$\sf \red{d=7}$

Answer 2

$\large \boxed{ \begin{array}{l} \rm \: d_{W,Z} = \sqrt{(( - 4) - 3) {}^{2} + (4 - 4) {}^{2} } \\ \\ \rm \: d_{W,Z} = \sqrt{ (- 4 - 3) {}^{2} + 0 {}^{2} } \\ \\ \rm \: d_{W,Z} = \sqrt{( - 7) {}^{2} + 0 {}^{2} } \\ \\ \rm \: d_{W,Z} = \sqrt{49 + 0} \\ \\ \rm \:d_{W,Z} = \sqrt{49} \\ \\ \boxed{ \boxed{ \rm{d_{W,Z} = 7}}}\end{array}}$
