Answer:
x = 3
Step-by-step explanation:
10x + 1 = 12x - 5
Subtract 1 from each side
10x = 12x - 6
Subtract 12x from each side
-2x = -6
Divided by -2
x = 3

Answer: odd
Step-by-step explanation:
Given
The graph of a function increases as x increases and decreases as x decreases.
This shows that the degree of the polynomial is odd
for example 
Here, the leading coefficient is positive, and the value of function increases as x increases and vice-versa.
8 x (5 x 2 + 3)= 8 x ( 15 + 3) = 8 x 13 = 104.
