Sounds like B to me because the problem has a solution! I would looooveee if you could head over an give me some help on my question?! thanks!
I'm not good at math i cant help
Let's factor the top and the bottom.
Top factors 4x + 20 = 4(x + 5)
Bottom x^2 + 2x - 15 = (x + 5)(x - 3)
The gcf is the largest value that will go into both the top and the bottom. In our problem the ONLY thing that will go into top and bottom is x + 5 so that is your GCF. (c)
Answer:
The unknown number is 2/15.
