6. Consider the statement For all real numbers 1 with r2 + 3r + 2 = 0, r2 = 1 or 2,2 = 4 Suppose you are trying to prove this statement. The structure of the proof could be (A) Supposeis a real number such that 2 +3r + 2-0 an(I deduce that x2-1 or x2-4. (B) Suppose is a real number such that r2 +3r+2 = 0 and deduce that r21 and x24. (C) Display 2 +3x + 2 = 0. (D) Display a real number r such that r21 and 24. a real number z such that 7. Consider the statement For every prime number p, p is odd Which of the following is true about this statement? (A) This statement is true. (B) This statement is false.

Explanation / Answer

Answer 7

the statement is false
