Answer:
(x-8) (x+7)
Step-by-step explanation:
x^2 -x-56
We want to factor this problem.
What two numbers multiply to negative 56 and add to -1
-8 *7 = -56
-8+7 = -1
We can use -8 and 7
(x-8) (x+7)
Check:
FOIL
first: x*x =x^2
outer: 7x
inner:-8x
last: -8*7 = -56
Add this together
x^2 +7x-8x -56 = x^2 -x-56

Answer:
-16
Step-by-step explanation:
The average of –25, –70, 15, –31, –25, and 40 is -16
To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;
The sum of the numbers is;
-25-70+15-31-25+40 = -96
We have a total of 6 values, thus the average becomes;
(-96)/6 = -16
