I will attach photo below.

Answer 1

Factor everything, find out what cancels, then simplify what's left.

Answer 2

I did and I got something like 4 - 4/75a * 7/2a -7/4
So I think I am doing it wrong >_<

Answer 3

\[\frac{3a^2-13a+4}{9a^2+6a+1}\frac{28+7a}{a^2-16}=\frac{(3a-1)(a-4)}{(3a-1)^2}\frac{7(a+4)}{(a+4)(a-4)}\]\[=\frac{7}{(3a-1)}\]

Answer 4

Thank you so much~!
I was way off. ^-^ Thank you again

Answer 5

No sweat. Do math every day.

Answer 6

Note: When I copied the problem, I made a sign error in the first denominator. The remainder of the problem is ok.
