Answer:

P=4x+9

Step-by-step explanation:

Basically, the problem is asking to make an triangle but without labeling its sides as number, but as algebraic expression.

So, let's say that all three sides are

AB=x+1\\BC=x+3\\AC=2x+5\\

Now, remember that the perimeter is the sum of all sides of a figure, so in this case would be

P=(x+1)+(x+3)+(2x+5)

To simplify this expression, we just need to reduce like terms as follows

P=(x+1)+(x+3)+(2x+5)\\P=(x+x+2x)+(1+3+5)\\P=4x+9

Therefore, the simplified expression of the perimeter is

P=4x+9

The image attached shows the triangle we used.
