Ответ:
Mean is 69 to get the mean you have to add all the numbers up and then count how many numbers there are all together and then divide it by the sum you got. The median is 70 to get the median you have to arrange all the numbers from least to greatest and then see which one is in the middle if there are 2 numbers then add them up and divide by 2 thats what I had to do to get 70. The mode is the most frequent number so the mode would be 71. That's all I can do for you I do not know the others sorry but hope this at least helped!

The given expression is
We need to determine the expression by factoring out the greatest common factor.
Also, we need to determine the factor of the entire expression completely.
Part A: Expression by factoring out the greatest common factor:
The GCF of two numbers is the highest number that divides both the numbers.
To rewrite the expression by factoring out the greatest common factor, we need to factor out the highest number that divides the two expressions.
Thus, we have;
Thus, the expression is
Part B: Factoring the entire expression:
Let us factor the entire expression.
(1)
Now, we shall factor the term
Applying the identity
Thus, we have;
(2)
Factoring the term , we get;
Thus, substituting the above value in equation (2), we get;
Factoring the term , we get;
Substituting the values in the equation (1), we get;
Thus, the factor of the expression is
