Answer:
12x+9
Step-by-step explanation:
We may find the perimeter of a shape by adding all of it's side lengths.
We can start by adding 2 sides together.
(5x+2)+(3x+8)=8x+10
Because we don't know the value of x, we can only add together the amount of times that it is multiplied.
Now we add the final side.
(8x+10)+(4x-1)=12x+9
Hope this helps friend.
