Answer:
Step-by-step explanation:
Let C(x) be the cost to produce x batches of widgets, and let R(x) be the revenue in thousands of dollars.
Profit function = Revenue - cost
So we get profit function by subtracting C(x) from R(x) using algebraic method of subtraction.
Profit function of x
=
you have negative -12
turn this into a positive (12)
12 plus 18
= 30
k=-16
-10=k+6
subtract 6 both both sides to isolate the variable
-16=k

What is the question?
w² +9w +20
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
