Explicação passo a passo:
[tex]\mathsf{d_{AB} = \sqrt{(x_B - x_A)^2 + (y_B - y_A)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(4 - (3))^2 + (0 - 0)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{(4 + 3)^2 + (0 - 0)^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{7^2 + 0^2}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{49 + 0}}[/tex]
[tex]\mathsf{d_{AB} = \sqrt{49}}[/tex]
[tex]\boxed{\boxed{\mathsf{d_{AB} = 7}}}[/tex]
