To solve this problem, you add all the numbers together and divide by the total amount of things. In this case, there are six scores, 210, 195, 213, 201, 226, and 155. You would add all of these things together, and then divide by six. All of these things added together equals 1,200. This divided by 6 is 200. David's average score would be a. 200. Hope this helps!
The value of b that makes x-2 a factor of x² - bx + b is 4.
Polynomial is an expression involving the operations of addition, subtraction, multiplication of variables.
Types of polynomials are quadratic, linear, cubic and so on.
The factor theorem states that; when f(k) = 0, then (x – k) is a factor of f(x).
Given that x-2 is a factor of x² - bx + b, hence:
f(2) = 2² - b(2) + b = 0
4 - 2b + b = 0
b = 4
Therefore the value of b that makes x-2 a factor of x² - bx + b is 4.

the answer is
the value of b is equal to
Answer:
-3=b
Step-by-step explanation:
since its a -4 u seperate it from the vari by dividing 12 by the -4 ( since -4b inplies multiplcation. u always do inverse operation.)
