Answer:
5x-1
Explanation:
So, to find the perimeter of a shape we will add up all the sides. The three sides are:
3x-5, 1-2x and 4x+3 and we will start by just adding plus signs between the three side equations and then adding like terms
3x-5+1-2x+4x+3 and now we can add all the terms with x's and all the terms that were just numbers
after we do that we get 5x-1
I hope this helps and please don't hesitate to ask if there is anything still unclear!
