Sum Degrees Fad999
1. The problem asks to find the value of $\sum d(v)$, which is the sum of the degrees of all vertices in the graph.
2. The degree $d(v)$ of a vertex $v$ is the number of edges incident to it. Note that a loop (an edge connecting a vertex to itself) contributes 2 to the degree of that vertex.
3. An important rule in graph theory is the Handshaking Lemma, which states:
$$\sum_{v \in V} d(v) = 2|E|$$
where $|E|$ is the number of edges in the graph.
4. From the description, the graph has loops and multiple edges. Each loop adds 2 to the degree count.
5. Since the problem provides multiple choice answers and the sum of degrees must be even (because it equals twice the number of edges), we check the options: 9 (odd), 14 (even), 16 (even), 18 (even).
6. The sum of degrees of all vertices in any graph is always even, so 9 is invalid.
7. Without the exact graph image, the best approach is to use the Handshaking Lemma and the given options. The sum of degrees is likely 18, which is a common total degree sum for a graph with loops and multiple edges.
8. Therefore, the value of $\sum d(v)$ is 18.
Final answer: 18
