Step-by-step explanation:
1) So you can get a similar denominator by multiplying by 5 and 4:
5(5x-4)+4(3x+2) / 20
And then simplify:
25x-20+12x+8 / 20
ANSWER: 37x-12/20
2) g is a function here so I'm not sure how to solve this, but in case it's f(g(x))...
5(-3x+1)-2
-15x+5-2
ANSWER (if f(g(x))): -15x+3
I'm not sure about the last one though, sorry. Hope this helped though. -w-
