Answers: 1
![\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)\implies 4\left( x+\cfrac{9}{2} \right) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 4x+18~\hfill](/tpl/images/0043/5953/157e0.png)
