Answer:
2 Tetrahedrons combined create an Octahedron.
Step-by-step explanation:
Despite the lack of information.
The Plato Polyhedrons are Tetahedron, Cube (Hexaedron), Dodecahedron, Octahedron and Icosahedron. They are regular ones, made up by regular plane figures.
An Octahedron can be built by combining two pyramids. Each Tetrahedron is made up by 4 equilateral triangle.

Answer:
where R is the R-value and t is the thickness in inches.
Step-by-step explanation:
We are given the following in the question:
The R-value of fiberglass insulation and f its thickness have a linear relation.
Let R be the R-value and t be the thickness. Then, the equation can be written as:
where a and b are constants.
When t = 3.5, R = 11
When t = 6, R = 19
Solving the two equation, using the elimination method, we have,
Thus, the linear relationship is given by:
where R is the R-value and t is the thickness in inches.
