<span>Formula : V + F – E = 2
where V = number if vertices, F = number of faces and E = number of edges
<u>Question a:</u>
V + F - E = 2
V = 2 - F + E
V = 2 - 12 + 18
V = 8
(a) </span><span>12 faces, 18 edges, <u>8</u> vertices
<u>Question b:</u>
</span>V + F - E = 2
<span>E = V+ F - 2
E = 14 + 8 - 2
E = 20
(b) </span><span>8 faces, <u>20</u> edges, 14 vertices</span>
2n=16 divide both sides by 2 you get n=8
Use distance formula to find length of each side:
RQ = 5.39
RS = 4.47
ST = 3.61
TU = 4.12
UQ = 8.54
Total =26.13
Answer = 26.1 Units
First you would take 312 and divide it by 13. Using that answer and put it over 1. Then times the answer that you just got by twelve. Then put that in a mixed number in its simplest form.
Answer: 
Step-by-step explanation:
Given: The Holy Roman Empire was a group of regions in Central Europe that was held together by a political union. The Holy Roman Empire was formed in the year 962.
Let x represent any year.
Now, the inequality in terms of x and 962 that is true only for values of x that represent years before the year that the Holy Roman Empire formed is given by :-
