pls, help I need this urgently!

Answer 1

Answer:

3v+15

Step-by-step explanation:

The perimeter P of a triangle is the sum of its sides so:

P = (v + 10) + (v + 10) + (v - 5)

so P = 3v + 15

Answer 2

Answer:

3v + 15

Step-by-step explanation:

To find the perimeter of a triangle we add all the sides

p = a+b+c

p = v + 10 + v + 10 + v - 5

p = 2v + 20 + v - 5

p = 3v + 15

I hope this helps :)
