<PRE><B>Question 81959</B>

Let x=length of base
then 4x-8=length of one of the equal legs


Now we are told that:
x+2(4x-8)=29  get rid of parens

x+8x-16=29  add 16 to both sides

x+8x-16+16=29+16  collect like terms

9x=45  divide both sides by 9

x=5 cm---------------------length of base

4x-8=4(5)-8=12cm------------length of one of the equal legs

CK

12+12+5=29
29=29

Hope this helps---ptaylor
