The perimeter of the triangle is 37 centimeters when one side is 3x cm the other side is 2x+1 cm and the last one is 2(x+4). solve for x and i'm so confused.
Add up the functions of x, equate the result to zero and then solve for x.
Verify for yourself that x = 4.
Solve the following for x:\[3x+(2x+1)+(2(x+4))=37 \]
