I believe the answer is 605 because I did 5 times 11 and 10
46 is your correct answer bc 30 plus 16 is 46
Answer:
howww!!11111111!!!!!!!!
Step-by-step explanation:
320 = 2x² - 12x as when there are an unknown number of rows there are 320 seats.
0 = 2x² - 12x - 320
0 = x² - 6x - 160
0 = (x - 16)(x + 10)
for this to = 0 one bracket must equal 0
therefore x = 16 or x = -10
not a negative number of rows.
Therefore must be 16.
It is not a function as it does not pass the vertical line test and as each x value is paired with more than one y value.
