1. Subtract 15 to the other side (5x^2 = 36)
2.Square root both sides to remove the squared of 5x^2 (sqrt(5x^2) = sqrt(36) simplified to 5x = 6)
3. divide by 5 to get x = 6/5
Final result is 6/5
Answer:
The limit converges to -1/5
Step-by-step explanation:
Plugging in infinity for n you will see that the limit will go to infinity/infinity so you have to apply L'Hopitals Rule
Doing so you find it will turn into the limit of (4-6)/10 as n goes to infinity. This then simplifies to -1/5
The sum of the question is 5.
