Question 1 of 8

Calculator allowed

Let \(n\) be the number of rows in the seating arrangement. Each row has \(n+2\) seats

The total is \(48\) seats

The meaningful domain is \(1\le n\le 11,\quad n\in\mathbb{Z}\)

(a)1 mark

Select the exact quadratic equation for this situation

n\left(n+2\right)=48

n\left(n+2\right)=50

n+\left(n+2\right)=48

n^2=48
