Answer:

y = -3 or 1

Step-by-step explanation:

In order to solve the polynomials, you need to add them and then factor:

5y - 2y² + 9 + 3y² - 12 - 3y

Combine like terms: y² + 2y - 3

Factor: (y + 3)(y - 1)

Solve for y: y + 3 = 0 and y - 1 = 0 or y = -3 or 1

all being said I think that the $148,000 is the answer that the question

Answer:

Step-by-step explanation:

Rick and Debbie are painting a large barn. Debbie paints twice as fast as Rick. They work together for 16 hours and complete the job. Determine how fast Debbie and Rick can paint the entire barn separately.

= 1/a + 1/2a = 1/16

= 2a + a/2a² = 1/16

2a/2a² = 1/16

= 1/a = 1/16
