Answer:
All expressions are correct
Step-by-step explanation:
9z+7z = 16 z
We need to find an expression ( or expressions ) that are equal to 16z
6z+3z+ 7z = 16z Correct
z+8z+7z = 16z Correct
z*16 = 16z Correct
21z+ -5z = 16z Correct

Answer:
The lesser number of workbooks are 1,000
Step-by-step explanation:
The correct question is
The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?
we have
For 
substitute in the equation and solve for b
Remember that the profit and the number of workbooks is in thousands
so
P=5

Using a graphing tool
Solve the cubic function
The solutions are
x=-1
x=1
x=5
therefore
The lesser number of workbooks are 1,000
<u><em>Verify</em></u>
For b=1
-----> is in thousands
so
----> is ok
