Q. What is the sign of 3xy 3 x y when x>0 x>0 and y<0 y<0 ?\newlineChoose 11 answer:\newline(A) Positive\newline(B) Negative\newline(c) Zero
  1. If xx is positive: If xx is greater than 00, then xx is positive.
  2. If yy is negative: If y < 0, then yy is negative.
  3. Multiplication rule: Multiplying a positive number by a negative number results in a negative number.
  4. Conclusion: Therefore, 3xy3xy is negative because 33 is positive, xx is positive, and yy is negative.
