6x+1=2(x+3)+4x has no solution because if you simplify it you get 6x+1=6x+3 which can not have any solution, since anything you substitute for x will not give you a solution.
4x-1=4(x+3) also has no solution. if you simplify you get 4x-1=4x+3 so no value that you substitute for x will give you a solution
Use the quadratic formula to get x = (3 - 2*sqrt(6))/3 or x = (3 + 2*sqrt(6))/3
Answer:
C it was the fastest way to do it when I was in class
The first square has side lengths of 4 units(because the square root of 16 is 4). The second square has side lengths of 8 units. The third square has side lengths of 12 units. As you can tell, the side lengths increase by 4. So the fourth square will have side lengths of 16 units, and the fifth square will have side lengths of 20 units. The question wants the perimeter, so the answer is 20*4(sum of 4 sides of equal lengths) which is 80 units.
The Problem which talks about correlation about Researchers studying senior citizens discovered that an elderly person's walking speed was correlated to that person's chance of living longer.
Also, it is given that The fastest walkers were more likely to live another 10 years than were the slowest walkers.
So, we can conclude from above statement that , elders who walks more has high correlation than the elders who do not take regular walk daily.
Yes, as walking makes our heart , body and mind strong, so chances of living becomes higher.
So, Elders who take walk regularly has high value of Positive correlation than person who does not take regular walk.
