Answer:
Regular Pentagon
Step-by-step explanation:
A regular icosahedron is a twenty-faced polyhedron, each face being an equiangular triangle. Each vertex is joined together by 5 faces, therefore the polygon formed at each vertex is a regular pentagon.
We can also figure out the number of faces at each vertex using Euler's formula
F+V=E+2
F=number of faces = 20
E=number of edges = number of triangular faces * edges/triangle /2
(since each edge is shared between two faces)
= 20*3/2
=30
Number of vertices
= E+2-F = 30+2-20 = 12
So number of edges meeting at each vertex
= 30 / (12/2) = 30/6 = 5
(12/2 because each edge joins two vertices).

Answer:
![m =-4](https://tex.z-dn.net/?f=m%20%3D-4)
Step-by-step explanation:
Given
![p(m-3 , -6) = p(-7 , -6)](https://tex.z-dn.net/?f=p%28m-3%20%2C%20-6%29%20%3D%20p%28-7%20%2C%20-6%29)
Required
Find m
![p(m-3 , -6) = p(-7 , -6)](https://tex.z-dn.net/?f=p%28m-3%20%2C%20-6%29%20%3D%20p%28-7%20%2C%20-6%29)
By comparison:
![m-3 = -7](https://tex.z-dn.net/?f=m-3%20%20%3D%20-7)
Add 3 to both sides
![m = -7+3](https://tex.z-dn.net/?f=m%20%3D%20-7%2B3)
![m =-4](https://tex.z-dn.net/?f=m%20%3D-4)
Answer:
complex number
Step-by-step explanation:
77i is an imaginary number but once you put that 3 in the equation it turns into a complex number bc its more than just the imaginary now
it would be the second one because it is exactly the same the first one is a little bit shorter so there not exactly the same
