Answer:
i would go for the first one but im not entirely sure
i suggest you wait to see other people's answers
Is the question number 2 you need help
Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
Answer:

Step-by-step explanation:
(5,9) and (2,3)
then by distance formula

d²=3²+6²
d²=9+36
d²=45

5/12 + 3/12 = 8/12
8/12 of the games are either sports or educational.
