If the number of the edges of the polyhedron is 14 and the vertices are 9. Then the number of the faces of the polyhedron is 7.
<h3>What is a
polyhedron?</h3>
A polyhedron is a solid made composed of polygons in three dimensions. It has vertices, flat faces, and straight edges.
We know the Euler's formula
F + V - E = 2,
where, F = number of faces, V = number of vertices, and E = number of edges
Edges: 14
Vertices: 9
F + 9 - 14 = 2
F = 14 + 2 - 9
F = 16 - 9
F = 7
Then the number of the faces of the polyhedron is 7.

To answer the item, we let x be the number of 2-point baskets and y be the 3-point basket, respectively. The system of linear equations that would allow us to express the given mathematically is,
x + y = 37
2x + 3y = 80
To determine the values of the variables, express x of the first equation in terms of y.
x = 37 - y
Substituting this to the second equation,
2(37 - y) + 3y = 80
The value of y from the equation is 6.
x = 37 - 6 = 31
<em>Answer: 31 two-point baskets</em>
Add 5/7 on both sides.
It'll cancel out the negative 5/7, and it will make the x variable only equal to one number (Well, a mixed number.)
D. because he says a little least and plus two of the other answer choices are negative so use process of elimination and D will be your answer.
