Question 781123
______________________________________________________________________________
The two equal SIDES of an isosceles triangle are three inches more then the base. If the perimeter is at least 121 inches, describe the length of the base.
______________________________________________________________________________



b = size of the base.
each side length is b+3.
'
Perimeter of the isosceles triangle would be {{{2(b+3)+b>=121}}}
{{{2b+6+b>=121}}}
{{{3b+6>=121}}}
{{{3b>=115}}}
{{{b>=115/3}}}
{{{highlight(b>=38&1/3)}}}
