The Answer would be 864mm^2
Answer:
40w^3
Step-by-step explanation:
I'm assuming you meant w^3 (w to the third power). In that case, you would just add 34 + 13 + 11 - 18 because they are all like terms (coefficients of w^3).
Answer: Mood
Step-by-step explanation: It would be mood because when you put it in a sentence it makes the most sense.
Example Sentence: The atmosphere of the room is sad.
The mood of the room is sad.
The other answers don't make as much sense. Hope this helps!
