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 are a rectangular prism and a pyramid different?

A pyramid is not a prism because it only has one base and a rectangular prism has 2 bases.Among other things, a rectangular prism has 6 faces, 8 vertices and 12 edges.A rectangular pyramid has 5 faces, 5 vertices and 8 edges.Rectangular prisms can be described as a "box". They do not have an apex (the vertice where all the edges meet. On the contrary, a pyramid does have an apex. It is located on the top of the pyramid.
