They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons. It has 8 faces and can have 6 to 12 vertices.
It has 9 vertices

They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons. It has 8 faces and can have 6 to 12 vertices.
No because they have 7 vertices
To determine how many heptagons can be formed by joining the vertices of a 10-sided polygon, we can use the combination formula. Specifically, we need to choose 7 vertices from the 10 available. This is calculated as ( \binom{10}{7} ), which is equal to ( \binom{10}{3} ) (since choosing 7 vertices to include is the same as choosing 3 vertices to exclude). Thus, ( \binom{10}{3} = \frac{10!}{3!(10-3)!} = 120 ). Therefore, 120 heptagons can be drawn by joining the vertices of a 10-sided polygon.
A heptagonal prism is a prism with a heptagon (7-sided polygon) as its base. It has 14 faces (2 heptagons and 12 rectangles), 20 vertices (2 at each corner of the heptagon and 2 at each corner of the rectangles), and 28 edges (7 edges on each heptagon base and 12 edges around the sides connecting the corresponding vertices of the base and top heptagon).

A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides altogether.
2*8 = 16 vertices.
It has 9 vertices
Has 2 vertices
A heptagon has 7 sides and so 2*7 = 14 sides
