Answer:52
Step-by-step explanation:
Answer:
2x-10
Step-by-step explanation:
So just add all of them together and you get 405. Then divide by the amount of numbers there is which is 5. So 405 divided by 5. The answer is 81.
Using Euler's Formula, the number of faces is given by: 8.
<h3>What does Euler's Formula states?</h3>
It states that the number of vertices, edges and faces is related by the following equation:
V - E + F = 2.
In this problem, the parameters are given as follows:
E = 15, V = 9.
Hence the number of faces is given by:
V - E + F = 2.
9 - 15 + F = 2
F - 6 = 2
F = 8.
