Answer:
4
Step-by-step explanation:
the Fundamental Theorem of Algebra states that for any polynomial of degree n, there are n roots, some of which may be complex
The polynomial shown is of degree 4 ( highest exponent of x )
Hence the polynomial has 4 roots/ zeros
-------------------------------------------------------------
Define x :
-------------------------------------------------------------
Let the numbers be x, x+2 and x+4
-------------------------------------------------------------
Construct equation :
-------------------------------------------------------------
The sum of these number is 69
x + x + 2 + x + 4 = 69
-------------------------------------------------------------
Solve x:
-------------------------------------------------------------
x + x + 2 + x + 4 = 69
3x + 6 = 69
3x = 63
x = 21
-------------------------------------------------------------
Find the numbers :
-------------------------------------------------------------
x = 21
x+ 2 = 23
x + 4 = 25
---------------------------------------------------------------------------
Answer: The third number in the sequence is 25.
----------------------------------------------------------------------------
(Simplified)
(First, Distribute)
12x-6y+2
(If you want it in standard form, subtract 2)
12x-6y=-2
