Which statement is NOT true?
x2 = 100 if and only if x = 10 or x = –10.
If x2 = 100, then x = 10.
If x = 10, then x2 = 100.
If x = –10, then x2 = 100.
The statement "If x = –10, then x2 = 100" is NOT true.
The statement that is NOT true is: "If x = –10, then x2 = 100."
Explanation: When x = -10, x^2 will equal 100, making the statement true.
