Which of the following choices uses deductive reasoning to show that the sum of any two odd integers is even? [1] A. (2r + 2) + (2y+ 2)=2(x + y +2) B. 3 + 5 -8 and 7 + 5=12 C. 2x + 2y+1 -2(:+3)+1 D. (2x + 1) +(2x +3)-2(2% + 2) 14. Rachelle made the following conjecture: "When you add a multiple of 6 and a multiple of 9, the sum will be a multiple of 3." Explain whether the following equation is a counterexample to this conjecture or verifies the conjecture. 18+27 - 45 [1] 15. Alison discovered a number trick in a book she was reading. the steps are shown in the table below. (2] Prove deductively that you always end up with the number you start with.
