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.

Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
The probability of the black sock is 6/26 for the white is 16/26 and for the brown is 4/26
Rational expression refers to a fraction in which the numerator and denominator are polynomials.
E. 5/15 since you multiply the numerator and denominator by 5.
D. 2/3 since you divide the numerator and denominator by 3.
W. 15/24 since you multiply the numerator and denominator by 3.
J. 4/5 since you divide the numerator and denominator by 5.
C. 48/54 since you multiply the numerator and denominator by 6.
G. 24/21 since you multiply the numerator and denominator by 3.
T. 27/36 since you multiply the numerator and denominator 3.
