Formulate and solve a quadratic problem

Question 1 of 8

Calculator allowed

Let \(s\) be the number of shelves in the display plan. Each shelf has \(s+2\) labels

The total is \(8\) labels

The meaningful domain is \(1\le s\le 10,\quad s\in\mathbb{Z}\)

(a)1 mark

Which equation models the stated relationship?

s+\left(s+2\right)=8

s\left(s+2\right)=8

s^2=8

s\left(s+2\right)=10

(d)1 mark

Which root values remain after the stated conditions are applied?

Use only the larger mathematical root

Use neither root

Use only the smaller mathematical root

Use both mathematical roots

(e)1 mark
