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
Now combine like terms to add the terms
2a+2a+3a becomes 7a
-3+1 is -2
Now the perimeter becomes
An expression to represents the perimeter is 7a-2
