What is the perimeter of a square with sides that measure 2x + 3 units?

8x+12

Step-by-step explanation:

We know that squares have equal sides. To calculate perimeter, just add up all of the 4 sides.

2x+3+2x+3+2x=3+2x+3

Add like terms:

8x+12

You could also multiply by four:

4 (2x+3)

Use distributive property:

8x+12
