1/3 of 81 = 81 • 1/3 = 81/3 = 27
Answer:
16 edges.
Step-by-step explanation:
We will use Euler's polyhedron formula to solve for the edges of our convex polyhedron.
Euler's polyhedron formula is:
, where,
V= Vertices of polyhedron,
F= Faces of polyhedron,
E= Edges of polyhedron.
Let us substitute V=6 and F=12 in Euler's formula to find number of edges of our polyhedron.
![6+12-E=2](https://tex.z-dn.net/?f=6%2B12-E%3D2)
![18-E=2](https://tex.z-dn.net/?f=18-E%3D2)
Let us subtract 18 from both sides of our equation.
![18-E-18=2-18](https://tex.z-dn.net/?f=18-E-18%3D2-18)
![-E=2-18](https://tex.z-dn.net/?f=-E%3D2-18)
![-E=-16](https://tex.z-dn.net/?f=-E%3D-16)
![E=16](https://tex.z-dn.net/?f=E%3D16)
Therefore, our convex polyhedron will have 16 edges.
I think the answer is C and I’m sorry if u get it wrong
<span> y – 2 = 4(x – 3)
y - 2 = 4x - 12
y - 2 = 4x - 12
y = 4x - 12 + 2
y = 4x - 10
y - 4x = -10</span>
I just took this and the answer is B
hope this helps!
