D) p = 11x

Quizplus · Accepted Answer

An isosceles triangle has two equal sides. In this case, those sides have lengths 5x. The third side, which is not equal to the other two, has length x.

The perimeter of a triangle is the sum of the lengths of its sides:

p = x + 5x + 5x

p = 11x

Therefore, the formula for the function that gives the perimeter of the isosceles triangle in terms of the length of one of its sides is p = 11x. So, the correct answer is choice D.
