In 1 and 2, use the table below that shows information about squares.
frutty [35]

1. The table has a constant of proportionality of 4, therefore, the perimeter and side length of squares are proportional.

2. Equation for the proportion is, y = 4x.

Perimeter = 48 cm.

<h3>What is the Equation of a Proportional Relationship?</h3>

The equation that defines a proportional relationship is, y = kx, where k is the constant of proportionality between variables x and y.

1. For the table given:

y = perimeter

x = side length

k = constant of proportionality = 8/2 = 16/4 = 24/6 = 4.

Since k is the same all through, the equation can be modelled as y = 4x, which means the perimeter and side length of squares are proportional.

2. Using the equation, y = 4x,the perimeter (y) of a square when its side length is 12 (x) is:

y = 4(12)

y = 48 cm.

The perimeter (y) of the square is: 48 cm.

How to find the volume
aev [14]

Answer: 1.44 centimeters cubed.

Step-by-step explanation:

To find the volume of a rectangular prism, use the following formula:

V=whl, where w equals the width, h equals the height, and l equals the length.

Substituting 0.6, 1, and 2.4 for the variables:

V = 0.6 * 1 * 2.4

V = 1.44 cm^3

The volume of the prism is 1.44 centimeters cubed.
