Which are zeros of the following polynomial?
1 answer:
Answer:
x = -2/3; x = 5/2.
Step-by-step explanation:
6x 2 - 11x - 10 = 0
Use the 'ac' method:
6 * -10 = -60. We need 2 numbers whose product is -60 and whose sum is -11.
That would be -15 and +4. So we write:
6x^2 - 15x + 4x - 10 = 0 Factor by grouping:
3x(2x - 5) + 2(2x - 5) = 0
(3x + 2)(2x - 5) = 0
x = -2/3; x = 5/2.

I'm really not sure but I'm pretty positive that this is the answer if not than my bad
Answer: -6 -2
Step-by-step explanation:
50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
They will meet back up in 40 minutes because 8x5=40 and 10x4=40 which 40 is both a multple of 8 and 10 so you're welcome
