Question

geometry the formula f + v = e + 2 shows the relationship between the number of faces f, edges e, and vertices v of a polyhedron, such as a pyramid. write the formula in words.
a) the sum of the number of faces and number of vertices is equal to the sum of two and the number of edges.
b) the product of the number of faces and number of vertices is equal to the product of two and the number of edges.
c) the sum of the number of faces and number of edges is equal to the sum of two and the number of vertices.

Explanation:

The formula $F + V=E + 2$ has addition on both sides. On the left - hand side, we have the sum of the number of faces ($F$) and vertices ($V$). On the right - hand side, we have the sum of the number of edges ($E$) and 2.

Answer:

A. The sum of the number of faces and number of vertices is equal to the sum of two and the number of edges.
