Question

calcule a distâncias entre os pontos a( -2,3) b(2,-1)

Preciso do cálculo, me ajudemmmm

Answer 1

$\mathsf{(x_{B}-x_{A})^2=(2-[-2])^2=(2+2)^2} \\\mathsf{ 4^2=16}$

$\mathsf{(y_{B}-y_{A})^2=(-1-3)^2=(-4)^2=16}$

$\mathsf{d_{A,B}=\sqrt{(x_{B}-x_{A})^2+(y_{B}-y_{A})^2}}$

$\mathsf{d_{A,B}=\sqrt{16+16}}\\\mathsf{d_{A, B}=\sqrt{2.16}}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{d_{A,B}=4\sqrt{2}}}}}}$
