Have a couple questions:
1) what is the solution of the proportion?
5/7=m/56
possible answers;
5/8
40
1/40
8
2) the polygons are similar. The smaller one is AD=12,DC=3, the bigger one JM=40,ML=x
possible answers;
17.3
10
120
160(my choice)

1.
5/7=m/56
Cross multiply and solve for x.
7m + 280
m = 40 
Thanks for the help on one problem

I was looking for how to do proportions, i had forgot.

You're welcome. Sorry I can't help you with the second problem.
