  Answer:

  A

  Step-by-step explanation:

  Consider the expression

  [tex]6x^2y-3+x^2y+2xy^2+2xy-6[/tex]

  which both girls are given.

  In this expression there are like terms:

  • [tex]6x^2y[/tex] and [tex]x^2y;[/tex]
  • [tex]-3[/tex] and [tex]-6.[/tex]

  Combine the like terms:

  [tex]6x^2y+x^2y=7x^2y;[/tex]

  [tex]-3+(-6)=-9[/tex]

  So,

  [tex]6x^2y-3+x^2y+2xy^2+2xy-6=7x^2y +2xy^2+2xy-9[/tex]

  Correct option is A, Salina combined the [tex]x^2y[/tex] terms correctly, but then left [tex]+x^2y[/tex] term in her answer.
