I think the answer is ozone i hope i am right and hope this helps
X = about 1 or x = about -2
9x^2 + 12x - 24 is standard form: ax^2 + bx + c
quadratic formula: x = (-b ± <span>√(b^2 - 4ac)) / 2a
x = -12 </span>± <span>√(12^2 - 4(9)(-24)) / 2(9)
</span>x = -12 ± <span>√(144 - (-864) / 18
</span>x = -12 ± <span>√(144 + 864) / 18
</span>x = -12 ± <span>√(1008) / 18
</span>x = -12 ± √(1008) / 18
x = −2 ± 2√7/3
x = -2 + 2√7/3 or x = -2 - 2√7/3
x = 1.0971675407097272 or x = −<span>2.4305008740430605</span>
The answer is B cause earth moon and sun combined together creates the greatest gravitational pull and makes tides.
