All this is, is plugging in numbers. Then taking the square root of it. The first one would be the square root of 6 squared - 4(5)(-3). That would simplify to the square root of 36+60. Then add the numbers to get the square root of 96. The square root of 96 is about 9.798. I hope that helped. If you still need help with the second one or with the rest of the formula (if there is one) just ask!

36 is more than 20 so the percentage is more than a hundred and less than 200% since 36 is less than 40. So if u subtract 20 from 36 and find that 16 is 80% of 20 and so when you add 100% to it, its 180%
