Step-by-step explanation:

Expand it, so you will get 9x^2 + 24x + 16
Answer:
11a − 29b − 50
Step-by-step explanation:
Subtract 7 from − 3
7a − 21b − 10 − 40 + 4a − 8b
Add 7a and 4a
11a - 21b - 10 - 40 - 8b
Subtract 8b from -21b
11a - 29b - 10 - 40
Subtract 40 from -10
11a - 29b - 50

Answer: Non proportional</h3>
Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.
The +100 at the end is why we don't have a proportional equation.
Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.
All you need to do is multiply the number of managers(210,000) by the number of dollars each one makes(39000). The answer would be $819,000,000 a year. You would not divide, just multiply the numbers.
