A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How many parallel edges and faces does a octahedron have?

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of parallel edges or faces will depend on the particular octahedron. A heptagon-based pyramid, for example, has no parallel edges nor parallel faces.

How many faces have perpendicular edges in a decagonal based prism?

Assuming a regular decagon is the base of the prism, it would be 10 faces. With an irregular decagon, it is possible that two (or more) of the edges of the decagons are perpendicular, so all 12 faces could have perpendicular edges.
