Answer:
-3x is the answer I'm pretty sure I think
Answer:
20
Step-by-step explanation:
Evaluate is just simplifying so
4 times 3 is 12 times the negative makes it -12
then add 32 and -12 together
and you get 20

In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)
Therefore the answer is 3mn (#3)
B 24a-22=-4(1-6a) has no solution
