Answer:
We know that the sum of the degrees of the vertices of the graph is twice the number of edges of the graph.
Let 
be a graph with vertices 
Then 
where 
is the number of edges of the graph. Since the graph is regular of degree r then all vertices have degree r. Thus,
Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that
a. First we adding x on both sides we get
Now, subtract 5 on both sides we get
b.
We are subtracting 9 from both sides we get
We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
Answer:
If the triangle is similar by any axiom then the ratio of their sides will be equal then you can easily find the side of the triangle
OR
You can also find it by congurency.

Find the domain of the given funciton
domain is numbers you can use in the function for x
so fractions
remember
never divide by 0
find what number makes denomenator 0 and restrict that
x-8=0
x=8
the domain is all real numbers except fo 8
