Answer:
14
Step-by-step explanation:
3*6=18
18-4=14
Graph is in the picture below
The last term will be the second part cubed or 6^3 which equals 216
Well I don't know where inequalities would come in but the third length would be solved as follows.
a^2+b^2=c^2
10^2+18^2=424

Answer;

I hope this is correct, its what I would do if I had this equation.
