For x = 5, which of the following correctly compares 2x and x²?
- A. x² is larger, because 25 > 10.Correct
- B. 2x is larger, because 10 > 25.
- C. They are equal.
- D. x² is larger, because 25 > 20.
Answer: A. x² is larger, because 25 > 10.
2(5) = 10 and 5² = 25.
Why the other answers are wrong
- B. 2x is larger, because 10 > 25.
- 10 is not greater than 25.
- C. They are equal.
- 10 ≠ 25.
- D. x² is larger, because 25 > 20.
- 2x is 10, not 20.
