    let's make x the number of weeks. What would you multiply x by i this formula?

    yes correct. So you multiply x by 2.3cm Now initially we have the tree at 7 meters. So we have to add it to the formular 7meters + x*2.3cm=y where y is the height of the tree after a certain number of weeks You can convert all the values to the same SI unit like turn cm into meters or meters into cm so that everything is the same
