Philip was asked to find the number of vertices of a polyhedron with 32 faces and 60 edges. What is his error? B45 F+E=V+2 32 + 60 = V +2 90 = V Choose the correct answer below. A. Philip did not add correctly. The polyhedron has 35 vertices. B. Philip misstated Euler's Formula. The formula should be F+V=E+2. The polyhedron has 30 vertices. OC. Philip swapped faces and edges. The polyhedron has 55 vertices. D. Philip misstated Euler's Formula. The formula should be F+V=E+2. The polyhedron has 20 vertices.

Edging a Planter A woman wants to make a small planter and surround it with edging material. She is deciding between two designs. Design 1: A square planter Design 2: A circular planter Edging material costs 3 a foot for the straight variety, which she would use for design 1 and 4 a foot for the flexible variety, which she would use for design 2. a If she decides on a perimeter of 24 ft, which design would give her the larger planting area? b If she decides to spend 120 on edging material, which design would give her the larger planting area?
