Question

Need help with number 10 please!

Answer 1

Answer:

5x-1

Step-by-step 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!

Answer 2

Answer:

5x - 1

Step-by-step explanation:

The perimeter is found by adding all the side lengths together. To write an expression for the perimeter of this figure, add up all the expressions for the side lengths.

(3x - 5) + (1 - 2x) + (4x + 3) = perimeter

Combine all like terms

5x - 1 is the final expression for the perimeter of the figure.
