Answer:
B
Step-by-step explanation:
We can get two equations from the inequality:
![3x+2>9\\3x+2>-9](https://tex.z-dn.net/?f=3x%2B2%3E9%5C%5C3x%2B2%3E-9)
We just need to simplify both equations to get our answers:
![3x+2>9\\3x>7\\x>\frac{7}{3}](https://tex.z-dn.net/?f=3x%2B2%3E9%5C%5C3x%3E7%5C%5Cx%3E%5Cfrac%7B7%7D%7B3%7D)
![3x+2>-9\\3x>-11\\x>\frac{-11}{3}](https://tex.z-dn.net/?f=3x%2B2%3E-9%5C%5C3x%3E-11%5C%5Cx%3E%5Cfrac%7B-11%7D%7B3%7D)
The two answers we get are:
![x\frac{7}{3}](https://tex.z-dn.net/?f=x%3C%5Cfrac%7B-11%7D%7B3%7D%5C%5Cx%3E%5Cfrac%7B7%7D%7B3%7D)
Which is also B.

Answer:
F is reduced by 31%
Step-by-step explanation:
F = 1/(d²)
now, we increase the distance by 20% (multiply by 1.2).
F new = 1/(1.2×d)² = 1/(1.44×d²) = (1/1.44) × (1/(d²)) =
= 1/1.44 × old F = 0.69 × old F
100 - 69 = 31%
