Respuesta :

The third one. It ends up to the same expression.
1/12 (-x+4) = -1/12x + 1/3 so A is not correct
1/12 (-x-4) = -1/12x - 1/3 so B is the correct answer
1/12 (-x-1/3) = -1/12x - 1/36 so C is not the correct answer
1/12 (-x-1/4) = -1/12x - 1/48 so D is not the correct answer

B is correct :)
