5. The equation \( R(x) = -5x^2 + 15x + 20 \) models the revenue (profit - costs) of a company in hundreds of thousands of dollars for every thousand units sold. Identify all key characteristics. How many units can the company sell and still make a profit?
2. Solve the equation for the value(s) of x. (There should be 2 answers for x value. Finding 1 is good enough for today ET, but if you find both x values and get 100 on today's ET, you can change a lowest ET to 100 in Q1.)
\[ x^2 + 6x = 16 \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c6a3dff-6729-485c-933e-bf615eefedb6%2F877e4154-6e73-4382-953f-be6b95382dcb%2Fbimale_processed.jpeg&w=3840&q=75)
