The following are examples of different contracts, after reading them, see whether each is void, voidable, unenforceable, valid, or something else, and briefly (one sentence) the explanation would be helpfull so I can understand why:

1.Zane, 17 years old, signed a contract for 12 months with T-mobile; he got a new Galaxy 9x, but had to pay $200 per month.

2.Sabra,a 20-year-oldjunior, and a Cornell chemical engineering student, was failing her large lecture (250 students) for Thermodynamics II.She made a written contract with her 4.0 GPA roommate Asha, who looked like Sabra, whereby Ashawould text formulasand answers to Sabra's Apple watch during the exam, and Asha would receive $100.

3.Kwame, 19 years old, signed a nine-month lease for a one-bedroom apartment in downtown Albany with Frankly Real Estate so he had a place to live during his sophomoreyear in college.
