Explicação passo a passo:
[tex]\mathsf{d_{AB} = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(1 - (-2))^2 + (0 - 3)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(1 + 2)^2 + (0 - 3)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(3)^2 + (-3)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{9 + 9}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{18}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{2.3^2}}[/tex]
[tex]\boxed{\boxed{\mathsf{d_{AB} = 3\sqrt{2}}}}[/tex]
