Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina

Answer: 1 Real Root
Step by Step Explanation:
The discriminant uses the formula b^2-4ac. (^ means an exponent, b squared up above)
a=1, b =4, c=4 sub in those values into the formula.
(4)^2-4(1)(4) = 0
Since the answer is 0, the equation will have 1 real root.
