16. IF X= 31, then what is the perimeter of triangle JMN?

180

Step-by-step explanation:

To solve we must first plug 31 into each expression for x.

2(31)+5= 67

3(31)-9= 84

31-2= 29

Then, remember that the perimeter is the sum of all of the sides. So add all of the previous sums, 67+84+29. Therefore, the answer is 180.
