Answer: 9 faces
Step-by-step explanation:
In geometry, we use Euler's formula, and it looks like this:
V − E + F = 2
where
V= the number of vertices of a polyhedron
E= the number of edges of a polyhedron
F= the number of faces of a polyhedron.
V = 9
E = 16
F = ?
9 - 16 + F = 2
F = 2 + 16 - 9
F = 9
D. (X-3)(4x)+(x-3)(2)
Answer: 2a/3 + b/3
Since it has two different variables, there is no final answer. To find the answer, you must first expand the equation and then apply the fraction rule.
Answer:
The answer is most likely C or D
