45.00x +17.99 = 422.99 (Setup Equation)
45.00x = 405 (Subtract 17.99 from both sides)
x = 9 (Divide both sides by 45.00)
To find the area of the path, we'll need to find the area of the space with the path and subtract the area of the inner space.
Total area: (80 + w)(50 + w)
Inner area: 80 x 50
Area of the path: (80 + w)(50 + w) - (80 x 50)
(4000 + 80w + 50w + w^2) - (4000)
4000 + 130w + w^2 - 4000
w^2 + 130w
w(w + 130)
Expression for the total area: (80 + w)(50 + w)
Expression for the area of the path: w(w + 130)
Hope this helps!! :)
Assuming the rate of phone calls is constant at 425 calls per month, you would have a proportional relationship between time and number of phone calls. In other words, the total phone calls would be dependent upon the number of months. i.e. 1 month = 425 calls, 2 months = 850 calls, and so on....
Therefore, for this relationship between time and total calls the following would be true.
The time( in months) would be considered the independent variable.
The number of calls for a specified number of months would be considered the dependent variable.
It means the figure is 1/4 the size of the original figure
