Answer:
i'd say b if im not right still working on it
Explanation:
Both are a number (6) multiplied by a variable (z).
However, 6z is the correct way to write this.
We usually write the number first, that's just the way it's done.
It sort of makes sense because 6z is literally equal to 6 z's.
I believe it is Star Wars, because you are adding on that you are watching that particular movie. The sentence would have been fine if you kept it its original way without the ",Star Wars." (We are watching one of my brothers favorite movies).
