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.

Answer:
2x + 50 = 100
Step-by-step explanation:
twice a number would be represented as 2x. And 50ore than that would be + 50. And since it equals 100 it would be = 100.
Answer:
10 m
Step-by-step explanation:
opposite = sin30° × 20 = 
× 20 = 10 m
K to the 6th power, because you can add k to k to the 5th power to make k to the 6th, and n to the 5th and n to the -5th cancel each other out.
