So you basically have, (27D-9)+3D = 29+(27D+1) 30D-9 = 27D+30 3D = 39 D = 13
A nonahedron
12d - 9 = 15d + 9 Subtract 15 d from both sides: -3d - 9 = 9 Add 9 to both sides: -3d = 18 Divide both sides by -3: d = -6
It is a nonahedron.
Here are the following shapes with 9 Vertices:NonahedronTriangular Prism
