Question

if x=3, then x square =9 A) x square =9 if and only if x=3, B) if x square, then x=3, C) x=3 if and only if x square =9, D) This statement is not reversible

Answer 1

(A) not true....because x could = -3 and x^2 would still = 9
(B) not always true....if x^2 = 9, then x could = - 3
(C) Not always true....x could = -3 and x^2 would be 9
That leaves D. You might want to get a second opinion.
