An octahedron in geometry is defined as a polyhedron with eight faces, six vertices and twelve edged. The term is used for regular octahedron mostly.
Thus we can summarize it as:
Number of edges: 12
Number of faces: 8
Number of faces: 6
the answer is 12 edges.
F(x)=x^2+3x-7, x=3
f(3)=3^2+3(3)-7
f(3)=9+9-7
f(3)=11

Answer:
18 and 42 are both multiples of 6, and when I add them, I also get a multiple of 6:
18+42=60.
Explain to Nina why adding two multiples of 6 will always result in another multiple of 6.
Step-by-step explanation:
18 and 42 are both multiples of 6 which means 6 is a factor of both numbers.
6⋅3=18
6⋅7=42

When you add 18 and 42, you can use the distributive property to show that the sum is also a multiple of 6:
6⋅3+6⋅7=6⋅(3+7)=6⋅10
