This is a fun one. Think of how the numbers have to be two in a row, so its asking which of those will multiply to 72?
Hope that helps you get started. Let me know if you need more help.
Answer:
- hexahedron: triangle or quadrilateral or pentagon
- icosahedron: quadrilateral or pentagon
Step-by-step explanation:
<u>Hexahedron</u>
A hexahedron has 6 faces. A <em>regular</em> hexahedron is a cube. 3 square faces meet at each vertex.
If the hexahedron is not regular, depending on how those faces are arranged, a slice near a vertex may intersect 3, 4, or 5 faces. The first attachment shows 3- and 4-edges meeting at a vertex. If those two vertices were merged, then there would be 5 edges meeting at the vertex of the resulting pentagonal pyramid.
A slice near a vertex may create a triangle, quadrilateral, or pentagon.
<u>Icosahedron</u>
An icosahedron has 20 faces. The faces of a <em>regular</em> icosahedron are all equilateral triangles. 5 triangles meet at each vertex.
If the icosahedron is not regular, depending on how the faces are arranged, a slice near the vertex may intersect from 3 to 19 faces.
A slice near a vertex may create a polygon of 3 to 19 sides..
Answer:

Step-by-step explanation:
Answer:
In 7.5 years, you will have $21,665.07 - $15,000 = $6,665.07 Interest
Step-by-step explanation:
Answer:
The Answer is approximately: 20.22
Step-by-step explanation:
The distance formula is:
d = Sqrt ((x - x1)^2 + (y - y1)2)
The points are (5, -14), (-15, -17)
d = Sqrt ((5 - (-15))^2 + (-14 - (-17))^2)
d = Sqrt ((5 + 15)^2 + (-14 + 17)^2)
d = Sqrt (20^2 + 3^2)
d = Sqrt (400 + 9)
d = Sqrt (409) = 20.22
