Which of the following are solutions?

We just try x=1 answer A and we see it works:

9(1²)+9(1)+1=19 good

That means the other root will be rational as well so x=-2 is the only other possibility:

9(-2)²+9(-2)+1=36-18+1=19 check

A F

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
