Answer: one side could be 2x+1 the for all three sides 3(2x+1)
Step-by-step explanation:
The 3 bieng how many sides amd 2x+1 is the expression for one side x being any number u choose.
Answer:
[tex]P=4x+9[/tex]
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
[tex]AB=x+1\\BC=x+3\\AC=2x+5\\[/tex]
Now, remember that the perimeter is the sum of all sides of a figure, so in this case would be
[tex]P=(x+1)+(x+3)+(2x+5)[/tex]
To simplify this expression, we just need to reduce like terms as follows
[tex]P=(x+1)+(x+3)+(2x+5)\\P=(x+x+2x)+(1+3+5)\\P=4x+9[/tex]
Therefore, the simplified expression of the perimeter is
[tex]P=4x+9[/tex]
The image attached shows the triangle we used.
