Question

read the description of a proportional relationship.
dana is finding the perimeter of different - sized squares. there is a proportional relationship between the side length of the square in inches, x, and the perimeter of the square in inches, y.
the equation that models this relationship is y = 4x.
what is the perimeter of a square with a side length of 4 inches? write your answer as a whole number or decimal.
inches

Explanation:

Step1: Identify the given values

We know the equation is \( y = 4x \), and the side length \( x = 4 \) inches.

Step2: Substitute x into the equation

Substitute \( x = 4 \) into \( y = 4x \), so \( y = 4\times4 \).

Step3: Calculate the result

\( 4\times4 = 16 \).

Answer:

16
