Answer:
X=-8
Step-by-step explanation:
113°-69°-52=x
-8=x
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
Answer:
Following are the solution to the given points:
Step-by-step explanation:

Each player's offer divided by the total number of players calculates the fair share
Ann's fair share 
Bob's fair share
Carol's fair share 
Denis's fair share 
Because Bob has the highest bid, that receives in the business.
Payments:
Ann
paid by estate
Bob
owes estate
Carol
paid by estate
Denis
paid by estate
Surplus
Splitting the equally among the four players. therefore one of the each receives:

The final settlement of the Ann receives:
