The perimeter of a square is 80-64y units. which expression can be used to show the side length of one side of the square?

a.16(5-4y) each side measures 5-4y units
b.16y(5-4) each side measures 5-4 units
c.4(20-16y) each side measures 20-16y units
d.4y(20-16) each side measures 20-16 units

Option C is correct

4(20-16y) each side measures 20-16y units

Step-by-step explanation:

The distributive property says that:

The perimeter(P) of a square is given by:

          .....[1]

As per the statement:

The perimeter of a square is 80-64y units

we can write this as:

Apply the distributive property we have;

⇒P = 4(20-16y)

On comparing with [1] we have;

Each Side length = 20-16y units

Therefore, an expression can be used to show the side length of one side of the square is, 4(20-16y) each side measures 20-16y units

you should at least use a calculater
