The answer is 7x-28, because if you put 7*x and 7*-4 the answer will be 7x and -28 if you distribute correclty.
Sure, I can look over it for you and give some suggestions, if need be.
A time that I often use acronyms is PEMDAS for math. PEMDAS stands for Parentheses Exponents Multiply Divide Add Subtract. This particular acronym is used for simplifying expressions with 2 or more operations. This was a very useful technique because it really stuck in the brain and helped me remember which order to simplify the expression.
Hope this helps :)
D - Hansel and Gretel must find a way to escape from the witch.
While answer A shows a conflict, their major conflict is with the witch. B is incorrect and they don't have any decision to make whether or not to stay and C is never mentioned in the text.
The action takes place in and around an old castle, sometimes
seemingly abandoned, sometimes occupied. The castle often contains secret passages,
trap doors, secret rooms, dark or hidden staircases, and possibly ruined sections. The
castle may be near or connected to caves, which lend their own haunting flavor with
their branches, claustrophobia, and mystery. (Translated into modern filmmaking, the
setting might be in an old house or mansion--or even a new house—where unusual
camera angles, sustained close ups during movement, and darkness or shadows create
the same sense of claustrophobia and entrapment.)
