9/2 or 4.5
hope this helps:)
Answer:
12g
Step-by-step explanation:
I don't have a lot of contexts here but based on what saw the answer should be 12g
So if you want to add
we distribute
a(b+c)=ab+ac so
-2(m+n-4)=-2m-2n+8
5(-2m+2n)=-10m+10n
n(m+4n-5)=mn+4n^2-5n
so total we ahve
-2m-2n+8-10m+10n+mn+4n^2-5n
group like terms
4n^2+-2m-10m-2n+10n-5n+mn+8
add like temrs
4n^2-12m+3n+mn+8
<span>n < 7k + 2p - 4 not too sure but i think this is right </span>
