x-8 is not a factor of 
Step-by-step explanation:
In order to check whether a term is factor of given expression or not we put the value in the expression. If the expression is zero, then the value is a factor otherwise not.
Given polynomial is:

We have to check if x-8 is factor of given polynomial or not. for that purpose we have to put

Putting in the polynomial

Hence,
x-8 is not a factor of

The divisibility rule for 12: A number is divisible by 12 if it's divisible by both 6 and 2. The reason for this is because 12 = 6 x 2.
This is a pythagorean theorem problem therefore a^2+b^2=c^2
a=8, b=?, c=10
8^2+b^2=10^2
64+b^2=100
100-64=56
square root of b^2=square root of 56
b=2 rad14
2 rad14 +4=
2 (rad14 + 1)= ANSWER
Answer:
Forget it, i'm confused
Step-by-step explanation:
(3x+2)+(5x-5)=8x-3
(17x-7)-(8x-3)=9x-10
Double Check
9x-10+5x-5+3x+2
17x-15+2
17x-13
