Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the lengt
h of the shortest side, and the third side will be twelve feet long. What expression could she write to determine the perimeter of the triangle if s represents the length of the shortest side? (Recall that perimeter is the distance around a shape.)
What is the expression in simplified form?
What is the coefficient of the variable in the simplified expression?
