When constructing a graph that compares the land areas of the five largest countries, you choose to depict the five areas with squares of different sizes. if the squares are drawn so that the areas are in proportion to the areas of the corresponding countries, is the resulting graph valid? why or why not? no, using area in graphs is always misleading. yes, using area in graphs is never misleading. yes, the variable of interest is two-dimensional. no, the variable of interest is two-dimensional.

The correct answer is:

      Yes, the variable of interest is two-dimensional.

Since we know that the area of a land of five largest countries is two-dimensional.

Also , if we are using a square figure which is also two-dimensional in order to describe the area of land then it would be valid because we just used a mathematical model of equal dimension to describe these lands.

       Hence, the answer is:

     Yes, the variable of interest is two-dimensional.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
