How many vertices does a convex polyhedron have if it has 14 faces and 24 edges?

The correct answer is C) 12

Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:

V - E + F = 2

We have 24 edges and 14 faces:
V - 24 + 14 = 2

Combining like terms,
V - 10 = 2

Add 10 to both sides:
V - 10 + 10 = 2 + 10

V = 12

boyakko [2]

{3}^{4}  \times  {3}^{ - 9}  =  {3}^{4}  \times (1/ {3}^{9}) =  {3}^{4} \div  {3}^{9}  \\  {3}^{(4 - 9)}  =  {3}^{ - 5}  = 1/( {3}^{5} )

Which is a graph for the inequality x&gt;2?
skad [1K]

Answer: The one you have selected is correct.

Step-by-step explanation:

Since x > 2 does not include the value of 2, the circle must be open.

The direction is to the right because it's every value which is bigger than 2.
