It's 3 units due to the fact that KF is = to 1 and you need it to have the same area of the triangle. So I got 3
Did I understand correctly, the first number is:

?
in other words, this would be:

and if you drink half of it, then we divide this number by 2:

because 30/2=15
so you would have

Answer:<em> </em><em>a)</em> 
<em> b) x₁ = - 14; x₂ = 6.</em>
Step-by-step explanation:
a) 4x² + 9x - 2 = 0
b) x² + 8x - 84 = 0

The answer is a. to be a function there can’t be an x value that is the same to a different y value. so as an example (6,7) (3,2) (5,6) (6,3) is not a function because 6 appears 2 times as an x value but with different y values. but you can have the same y value.
