-117 must be added to complete the square.
B.
2/0.8 is 2.5
I would download an app called Socratic is helps a lot!
X = 0.2 or 1/5
5^3 (5 squared) equals to 125. We'd have to figure out what could multiply by 125 to get 25, which is 0.2. It couldn't be a number over 1 since that would equal to a product larger than 125.
simplifying:
0.2 = 2/10 = 1/5
Hope this helps! :)
