Step-by-step explanation:
so you divide
![80 \div 20 = 4](https://tex.z-dn.net/?f=80%20%5Cdiv%2020%20%20%3D%204)
so each t-shirt costs 4$
Combine like terms. remember to keep the signs.
5x² - 2x² = 3x²
3x - (-6x) = 3x + 6x = 9x
4 - (-3) = 7
3x² + 9x + 7 = Ax² + Bx + C
9 = B, because 9 is in the B's place
9 is your answer
