We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion: 

So discriminant gives us 3 possibilites connected with result of the equation b^2-4ac. If it is bigger than zero, there are 2 solutions, if answer is exactly 0, then there is one answer and if the number is lower than 0, there are no solutions.
Discriminant of your quadratic equation is (-4)^2-4*1*5=16-20=-4, so there are no solutions.
I think it 4194304 i THINK thats the answer
Answer:
D
Step-by-step explanation:
From the box- plot the left hand side of the box represents the lower quartile
that is
= 2 → D
