1. Which is equivalent to the expression below?<br> (3.x2 – 2x + 5) - (2x2 – 5x + 1)
Nana76 [90]

Answer:

x = 6

x = 1

Step-by-step explanation:

(3x² - 2x + 5) - (2x² - 5x + 1)

= 3x² - 2x² - 2x - 5x + 5 + 1

= x² - 7x + 6

= (x - 6)(x - 1)

x - 6 = 0

x = 6

x - 1 = 0

horsena [70]

Answer:

1194 bleacher tickets

Step-by-step explanation:

If all were grandstand tickets, revenue would be 0.65*5716 = 3715.40. It was actually 298.50 less than that. Each bleacher ticket sold drops the revenue by .25, so there were 298.50/.25 = 1194 bleacher tickets sold.
