Which document established a process for new territories to become states within the united states? a. declairation of independence. b. articles of confederation. c. bill of rights d. northwest ordinance. really need answers

Hey! 
So ..
A is out because the declaration of independence doesn't talk about getting territories , it just talks  about how the U.S gained Independence at long last from Britain
B is out because the Articles of Confederation basically was an early "failed" constitution that could not place taxes.

C is out . bill of rights is just a list of rights that we as people have and how these rights are protected and can not be taken away from us.

D is your answer...
The Northwest Ordinance was a document that was passed July 13, 1787 which established a process for new states to be gained and they can become part of the U.S territory.

Hope this helped :)
