(4^2+8^2)^.5 = 8.944
It's not 12.
So 4,8,12 can't be the side lengths of a right triangle.
The parabola opens down, since the 'a' value of the equation is a negative value.
We are given with the total number of library books of 66. 18 of these 66 books were classified as fiction while the remaining are non-fiction books. The ratio of non-Fiction to fiction can be determined by first finding out the number of non-fiction books. that is 66-18 or 48 books.The ratio then is 48/18 or 8/3.
The answer is D. x+y=4
hope this will help
