Step-by-step explanation: so for the first one you have your equation 18+4(m-3)+4m you take the second part and do 2(9+2(m-3)+2m) then after that you get 2(9+2m-6+2m)  and you get you first answer 2(3+4m)

Your second probelm 6+8m you have your equation 18+4(m-3)+4m  you do 18+4m-12+4 and you subtract all th likes terms so you get 6+8m

Hope this helps!
