Select the correct answer.
A triangle has side lengths of n, n - 3, and 2(n - 2). If the perimeter of the triangle is at least 37 units, what is the value of n?

Respuesta :

Answer:

n = 11

Step-by-step explanation:

Perimeter =  sum of all the sides

n + n - 3 + 2(n-2) = 37 units

n + n - 3 + 2n - 4 = 37             {Combine like terms}

n + n + 2n - 3 - 4  = 37

                 4n - 7 = 37

                       4n= 37 + 7

                       4n = 44

                         n = 44/4

n = 11
