Answer:
40
Step-by-step explanation:
if you used cross products you'd pair 8 with 100 and n with 20
That written out would be 8(100)=20n
8(100)=800
800=20n
Divide on both sides
800/20=40
20/20 (cancels out)
Therefore n=40

Answer:
7m^4-52m^3-28m^2+67m+42
Step-by-step explanation:
(7m^2-3m-7)(m^2-7m-6)
7m^4-3m^3-7m^2-49m^3+21m^2+49m-42m^2+18m+42
7m^4-3m^3-49m^3-7m^2+21m^2-42m^2+49m+18m+42
7m^4-52m^3-28m^2+67m+42
