Adding all of the expressions together, (2a-3+2a+3a+1), would equal 7a-2. I hope my answer helps!
Answer:
7a-2
Step-by-step explanation:
to represent the perimeter of 2a-3 and 2a and 3a+1
The given sides are 2a-3 and 2a and 3a+1
To find out the perimeter we add all the sides
[tex]Perimeter = 2a-3 +2a+3a+1[/tex]
Now combine like terms to add the terms
2a+2a+3a becomes 7a
-3+1 is -2
Now the perimeter becomes
[tex]Perimeter = 2a-3 +2a+3a+1[/tex]
[tex]Perimeter = 7a-2[/tex]
An expression to represents the perimeter is 7a-2
