Answer:
k = 4
Step-by-step explanation:
In order for the claim to be true, (x-3) must be a factor of each of the terms in the first expression. That is, you must have that expression factor as ...
(x -3)(2x +5) +(x -3)(x +7)
Factoring out (x -3), we get ...
= (x -3)(2x +5 +x +7) = (x -3)(3x +12)
= 3(x -3)(x +4)
The value of k must be 4.

Answer:
Step-by-step explanation:
The first differences are 8, 13, 21. The second differences are 5, 8. The second differences are not constant, so this is <em>not a quadratic sequence</em>.
If we assume it is a cubic sequence, a calculator tells us the formula is ...
X=2
Explanation:
2x+14=18
-14 -14
2x=4
Divide 2 with 4 which makes the 2 with the x cancel out. The two 14s cancel out by the way.
So 4 divided by 2 equals 2.
1/8 is equivalent to 0.125. I hope this helps!
