A convex polyhedron has faces that consist of 1 pentagon, 5 congruent equilateral triangles, and 5 congruent
squares. The solid has 11 vertices. How many edges does this solid have?

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

Icould really use some with this question.

Could somebody me with this radical simplification?
