Answer:
A/2 approximately
Step-by-step explanation:
The sign has two sides. She painted one of them. So that's 1/2. I said "approximately" because I assumed a 4-sided post. Maybe it is a round post and painting "one side" is possible.
Combine like terms
-7y² + 6y² - 2y² = -3y²
4y + (-5y) - (-9y) = 4y - 5y + 9y = 8y
9 + 9 - (-2) = 9 + 9 + 2 = 20
-3y² + 8y + 20 is your answer
