Question

Write an expression to represent the perimeter of 2a-3 and 2a and 3a+1

Answer 1

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

$Perimeter = 2a-3 +2a+3a+1$

Now combine like terms to add the terms

2a+2a+3a becomes 7a

-3+1 is -2

Now the perimeter becomes

$Perimeter = 2a-3 +2a+3a+1$

$Perimeter = 7a-2$

An expression to represents the perimeter is 7a-2

Answer 2

Adding all of the expressions together, (2a-3+2a+3a+1), would equal 7a-2. I hope my answer helps!
