Answer:
$532
Step-by-step explanation:
Hey There!
So to solve this problem the first thing that we want to do is find the cost of 1 ball
To do so we divide the total cost of 10 balls by 10
280/10=28 so each ball cost 28
now to find the cost of 19 balls we multiply the cost of 1 ball by 19
18x28=532
thus meaning 19 balls cost $532
Answer:

The general form of the quadratic equation is :
The discriminant is :
And the general solution is :
![x=\frac{-b\pm\sqrt[]{D}}{2\cdot a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7BD%7D%7D%7B2%5Ccdot%20a%7D)
So, there are 3 situations for D
1. D = 0
So, the roots of a quadratic equation are two similar roots
2. D > 0
so, roots of a quadratic equation are two different roots
3. D < 0
so, roots of a quadratic equation are not real, two comlex roots
