Answer=1) El mesero
This is because this is a masculine singular and waiters usually wear a uniform
3x23x2= 138 feet wide by 28xy + 10x6y + 2 feet long B) purchase 140 feet X (28xy + 10x6y) fencing
No hay nada encima de la mesa. If you sound it out, it could either be "nada" or "nadie" but if you are talking about an object, then use "nada". If you are talking about someone not on the table, you would use "nadie" Nada: for object, Nadie: for person.
Hope this helped
