A mockingbird symbolizes innocent. Harper Lee probably has Jem and Scout hear a mockingbird as they're walking to their school alone because through the story they symbolize the innocence of youth, sheltered in their community. The action of the novel has them experiencing things far beyond what they ever have before and trying to maintain their innocence.
Based on the given excerpt above which is taken from "To Kill a Mocking Bird", it shows the Scout is evoking the shooting of the rabid dog. This is the scene about the Mad Dog. The answer would be the third option. Hope this answer helps.
I believe the best answer for this would be A. Exclamatory
Original equation: 5c-4-2c+1=8c+2
The first thing you want to do is combine like terms:
3c-3=8c+2
Then. get the variable on its own side by subtracting the 3c from the left and subtracting the 2 from the right:
-5=5c
Divide both sides by 5 to get c by itself:
-1=c
