m equals the sum of m1 and m2m is equal to m1 plus m2 plus onem corresponds to m1 added to m2 plus twom is the sum of m1 and m2 plus threem is twice m1 plus m2

Explanation

For a compound truss formed by two simple trusses with member counts m1 and m2, the total number of members m must satisfy m = m1 + m2 + 3 to ensure the structure is both rigid and statically determinate.
