Question 1063276
Starting from zero height, the equation would be
{{{ h = 26t }}}
{{{ h }}} = height in cm 
{{{ t }}} = time in years 
------------------------
{{{ h = 292 }}} cm 
{{{ 292 = 26t }}}
{{{ t = 11.23 }}}
{{{ 11.23 - 4.5 = 6.73 }}}
---------------------------

The tree had grown for 6.73 yrs before 
Vlad moved into house
{{{ h = 26t }}}
{{{ h = 26*6.73 }}}
{{{ h = 174.98 }}}
It was 175 cm tall when he moved in
-------------------------------------
{{{ h = 26t }}}
{{{ 357 = 26t }}}
{{{ t = 13.73 }}} yrs
{{{ 13.73 - 6.73 = 7 }}}
7 yrs after he moved in, the tree was 357 cm tall

Definitely get a 2nd opinion on this
& check the math
