Answer:
D,E
Step-by-step explanation:
Distance between C and D =sr( (-7 - -10)^2 + (6 - 2)^2) = sr(3^2 + 4^2) = sr(9 + 16) = sr(25) = 5 units
The answer is C.3 I did this one on my credit recovery
If the number of the edges of the polyhedron is 14 and the vertices are 9. Then the number of the faces of the polyhedron is 7.
<h3>What is a
polyhedron?</h3>
A polyhedron is a solid made composed of polygons in three dimensions. It has vertices, flat faces, and straight edges.
We know the Euler's formula
F + V - E = 2,
where, F = number of faces, V = number of vertices, and E = number of edges
Edges: 14
Vertices: 9
F + 9 - 14 = 2
F = 14 + 2 - 9
F = 16 - 9
F = 7
Then the number of the faces of the polyhedron is 7.
