A triangle has side lengths of (x+4), (4x8), and (2x+8) units. If the perimeter of the triangle is at least 88units, what is the minimum length of each side of the triangle?

oh that's easy you just equal everything to 88 units...
1. add everything together... so 7x+4
2. equal to 88
3. Solve!
7x+4=88
thenn... you have x to figure out each side
