2 answers:
Answer: 13/20
Step-by-step explanation:
Total number of beads: 20+14+10+28+8=80
Green beads out of the total 80: 28
Non-green beads out of the total 80: 80-28=52
The probability of Christina choosing a bead that is not green is the number if non-green beads divided by the total number of beads, so 52/80, which simplifies to 13/20

Answer:
(2, -6)
Step-by-step explanation:
5n^2+20n-60
(5n+30)(n-2)
5n + 30 = 0
5n = -30
(5n = -30)/5
n = - 6
n - 2 = 0
n = 2
answer: (2, -6)
