Concept explainers
Here we celeb rate the power of algebra as a powerful way of finding unknown quarnities by naming them, of expressing infinitely many relationships and connections clearly and succinctly, and of uncovering pattern and structure.
Small again. Let E denote the number of edges and V denote the number of vertices for the solid Small R from Mindscape 30. The values of E and V satisfy the equations
Find the values of E and V.
