Answer:
x = 2
Step-by-step explanation:
Start by combining like terms.
Collecting x terms onto the left side results in 8x;
collecting constants onto the right side results in 16.
Therefore, 8x = 16, and x = 2
A = 11/5, let me know if you need me to tell you how i got it (show my work)
Answer:
There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function:
And Odd one: 
Step-by-step explanation:
1) Firstly let's remember the definition of Even and Odd function.
An Even function satisfies this relation:

An Odd function satisfies that:

2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:



3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely,
and
for odd functions.
Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
