The total number of seats in an auditorium is modeled by f(x) = 2x2 - 6x, where x represents the number of rows of seats. how many rows are there in the auditorium if it has a total of 416 seats?

Since there can't be negative number of rows, the answer is 16.

 The number of rows is 16.

Step-by-step explanation:  Given that the total number of seats in an auditorium is modeled by the following equation:

where x represents the number of rows of seats.

We are to find the number of rows are there in the auditorium with a total of 416 seats.

So, we are to find the value of x if f(x) = 416.

We have

Since the number of rows cannot be negative, so the required number of rows in the auditorium is 16.

Thus, the number f rows is 16.

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
