Answer: 42
Step-by-step explanation:
Let the six consecutive even numbers be x , x+2 , x+4 ,x+6 ,x+8 ,x+10.
Then According to the question , we have

Now, the second number from the above six consecutive even numbers is x+2.
Substitute the value of x in it, we get
The second number in this sequence = 
Answer:
C. x^5/2 + 6x^3/2 + 1.
Step-by-step explanation:
(x^3 + 6x^2 + x^1/2) / x^1/2
= x^(3 - 1/2) + 6 x(2-1/2) + 1
= x^5/2 + 6x^3/2 + 1.
Answer:
Contradiction
Step-by-step explanation:
Suppose that G has more than one cycle and let C be one of the cycles of G, if we remove one of the edges of C from G, then by our supposition the new graph G' would have a cycle. However, the number of edges of G' is equal to m-1=n-1 and G' has the same vertices of G, which means that n is the number of vertices of G. Therefore, the number of edges of G' is equal to the number of vertices of G' minus 1, which tells us that G' is a tree (it has no cycles), and so we get a contradiction.
Answer:
138
Step-by-step explanation:
Hexagon total angle = 720
170+ 277 + 135 = 582
720 - 582 = 138
X = - 1/3 or an alternate form x = -0.3, x = -3 to the power of -1
