Question 81849: The length of one of the equal legs of an isosceles triangle is 8 cm less than 4 times the length of the base. If the perimeter is 29 cm, find the length of one of the equal legs.
I am thinking the formula would at least maybe start out as: 2(4x-8) + x = 29 ???

Question 82008: Here is my problem: The hypotenuse of a right triangle is 1cm more than twice the shorter leg, and the longer leg is 9cm less than three times the shorter leg. Find the lengths of the three sides of the triangle.
I know that (pythagorean theorem), so if a is the shorter leg, I would get: So if I follow what I think I know about solving equations, I wind up with which I can simplify down to . This is where I get stuck. I'm not sure how to solve for a with in the equation, and if I try to factor out the a I am getting a negitive, never ending number for a.
