Final answer:
The equivalent expression for the perimeter of a square given as (16x+4) is (4x+1).
Step-by-step explanation:
To find the equivalent expression for the perimeter of a square, which is given as (16x+4), we need to simplify it. The perimeter of a square is calculated by multiplying the length of one side by 4. In this case, the length of one side is (16x+4)/4, which simplifies to 4x+1. Therefore, the equivalent expression is (4x+1).
