Question

the area of a square depends on the length of its sides. answer the questions below regarding the relationship between the area of the square and the length of one side of the square. answer attempt 1 out of 2 the independent variable, x, represents the , and the dependent variable is the , because the depends on the . a function relating these variables is r(x)= . so r(7)= , meaning if 7

Explanation:

Step1: Identify variables

The side - length is independent. Area depends on side - length.

Step2: Define function

Area of square $A = s^2$, so $R(x)=x^2$.

Step3: Evaluate function

$R(7)=7^2 = 49$.

Answer:

The independent variable, $x$, represents the length of one side of the square, and the dependent variable is the area of the square, because the area depends on the length of one side of the square. A function relating these variables is $R(x)=x^2$. So $R(7)=49$, meaning if the length of one side of the square is 7, the area of the square is 49.
