The sides of a triangle are (2x+1), (x+6), and (3x-4). What is the expression for its perimeter?

Answer and explanation

Correct answer: \(6x+3\)

The perimeter of a triangle is the sum of its three sides. Thus, \((2x+1)+(x+6)+(3x-4)=2x+x+3x+1+6-4=6x+3\). Hence, the correct expression is \(6x+3\). In \(6x+11\), the constant terms have been added incorrectly. In exams, combine like terms by adding the \(x\)-terms and constants separately.
