For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional. If x = 3, then x2 = 9. If x2 = 9, then x = 3. x2 = 9 if and only if x = 3. If x2 = 3, then x = 9. If x2 = 9, then x = 3. x = 3 if and only if x2 = 9. If x2 = 9, then x = 3.
