Question 380449: Use an inequality to solve the problem. Be sure to show the inequality and all of your work.
One side of a triangle is 2 cm shorter than the base, x. The other side is 8 cm longer than the base. What lengths of the base will allow the perimeter of the triangle to be at least 30 cm?

You can put this solution on YOUR website!
base =x
one side = x-2
other side = x+8
..
the perimeter should be at least 30 if not more
x+x-2+x+8>=30
3x+6>=30
-6
3x-6+6>=36
3x>=24
/3
x>=8
