Step-by-step explanation:
2√5
Based on observation, in this polyhedron, there are a total of six vertices, nine edges, and five faces.
<h3>What are vertices?</h3>
In geometry, this refers to the point where two line meet. In this case, the vertices are A, B, C, D, E, F for a total of six vertices.
<h3>What are the edges?</h3>
This term refers to line segments, for example the line between B and C is an edge. Based on this, there are nine edges in this shape.
<h3>What are faces?</h3>
This refers to flat surfaces; in this, case the total of flat surfaces are five.

Step-by-step explanation:
4x dived by 2. X equals 2 -1(2) =1
I don’t understand the question you’re asking? If you could give more context I would love to help!
Answer:
x = -1
Step-by-step explanation:
-2(x - 5) = 12
-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)
-2x = 12 - 10
-2x = 2
x = 2/(-2)
x = -1
