Question 1066315: The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 21 cm and a second side that is 3 cm less than twice the third side, what are the possible lengths for the second and third sides?

You can put this solution on YOUR website! The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 21 cm and a second side that is 3 cm less than twice the third side, what are the possible lengths for the second and third sides?
1st side:: 21 cm
2nd side: 2x-3 cm
3rd side: x
------
Equations because sum of 2 sides must be greater that remaining side:
2x-3+21 > x
3x-3+x > 21
x+21 > 2x-3
---------------------
Modify::
x+18 > 0
4x > 24
x < 24
----
3rd side:: 6 < x < 24
2nd side:: 9< 2x-3 < 45
