Question

For a class project, Zachary made a square-shaped model of the park near his house. Each side of his model is x inches long.

Pick all the expressions that represent the perimeter of Zachary's model.

4=x

x^4

4x

x+x+x+x

Answer 1

Can you please pick one

Answer 2

The perimeter of a square is the sum of the lengths of all four sides. Since each side of Zachary's model is x inches long, the expressions that represent the perimeter of his model are:

4x (because there are four sides and each side is x inches)

x + x + x + x (because this is simply adding the length of each side)

Hence, the correct expressions from the options provided are:

4x
x + x + x + x

The expressions "4=x" and "x^4" do not represent the perimeter. "4=x" is an equation suggesting that 4 equals x, which doesn't describe the perimeter. "x^4" represents x raised to the fourth power, which is not the same as adding the sides of the square.

Answer 3

Certainly! If you need to pick just one expression that represents the perimeter of Zachary's square model, the most standard and concise representation would be:

**4x**

This expression denotes that each of the four sides of the square has a length of x inches, and when you add all four sides together, you get the perimeter.
