A square has a side length of 2x+5, write an expression to find the perimeter of the square

4(2x+5) or 8x+20

Step-by-step explanation:

8x + 20

Step-by-step explanation:

Side = 2x + 5

Perimeter of square = 4*side

                                 = 4*(2x + 5)          {Use distributive rule:a(b +c) = a*b +a*c}

                                = 4*2x + 4*5

                                = 8x + 20

not sure but it may be b, as i said i'm not sure.
