<PRE><B>Question 175554</B>
height of hemlock:lets call h
height of spruce :lets call s
call time t
:
h=4t+14
:
s=6t+8
:
we want to know when those will be equal in other words when h=s. So set the equation values of each of those equal to each other
:
4t+14=6t+8
:
2t=6
:
{{{highlight(t=3)}}}years
:
{{{highlight(h=4(3)+14=26)}}}inches
{{{highlight(s=6(3)+8=26)}}}inches
