Question

Find the length of the apartment in terms of x.

Answer 1

We have to find the length of the apartment in terms of x. This is, we will sum the lengths of the rooms, thus:

$x+(x+5)+(2x-1)+x+(x+8)$

Simplifying, we obtain:

$\begin{gathered} =x+x+5+2x-1+x+x+8 \\ =6x+12 \end{gathered}$

This means that the length of the apartment is 6x+12.
