The answer is 14 (D).

7 is greater than or equal to 7.
Answer:
<u>Given equations</u>: y = 3x² + x - 6; y = x - 4
So, Plug the value of value of y in other equation
- 3x² + x - 6 = x - 4
- 3x² + x - x - 6 + 4 = 0
- 3x² - 2 = 0
- 3x² = 2
- x² = 2/3
- x = √2/3
17 * 39 = 331.5 * 2
17 * 97 = 824.5 * 2
