Answer:
The number of the sums that are composite numbers is;
[tex]2[/tex]Explanation:
Composite numbers that have more than two factors. they are numbers that can be derived by multiplying two smaller numbers.
From the sums let us identify the composite numbers using their factors;
[tex]\begin{gathered} 7\rightarrow1,7\text{ ----- not composite} \\ 16\rightarrow1,2,4,8,16\text{ ----- composite} \\ 36\rightarrow1,2,3,4,6,12,18,36\text{ ------- composite } \\ 43\rightarrow1,43\text{ --------- not composite} \end{gathered}[/tex]Therefore, the number of the sums that are composite numbers are;
