Answer:
The results are statistically significant because planting hardwood trees have a higher profit per acre.
Step-by-step explanation:
From the question above,
It shows that hardwood trees had a 46% higher Profit per acre than softwood trees.
Meaning that for every $100 made on softwood trees, $146 profit would be made on hardwood trees i(including both primary and secondary expenses; making the hardwood trees more profitable.
The information given is enough to reach a conclusion that planting hardwood trees have a higher profit per acre than softwood trees.
If it's just distribution, not solving for s (I mean I could but do you need to?):
5(2s² - 3s + 4) Distribute/multiply 5 into (2s² - 3s + 4)
(5)2s² - (5)3s + (5)4
10s² - 15s + 20
28,000+3,000x=36,000+2,000x
X will be the number of years worked, now we just have to make the equation true.
I did the work out already, and the answer is 8!
If you want to check my answer just substitute it in to the problem for x.
