Answer:
a cant exist because 3 out of the 4 vertices must have only one degree vertex and the remaining one must have 5.
b) This example can be a single graph because of the handshaking lemma. The sum of the odd degrees vertex must be an even number: 3+3+5=11
In the number 7.46, the number in the ones place is 7. The 4 in the tenths place is 0.4. The number in the hundredths place is 0.06.
