A convex polyhedron has 18 edges and 4 more vertices than faces. How many faces does the polyhedron have? Euler’s formula: V + F = E + 2

8
12
14
16

8 faces

Step-by-step explanation:

F = # faces

4 + F + F = 18 + 2

2F + 4 = 20

2F = 16

F = 8

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
