The expression 17n+11 represents the perimeter of the triangle.

a simplified expression that represents the measure of the third side is

the answer is 8n

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

c: lkllmn.

hope it's you
