Enter a simplified expression to represent the situation. A square swimming pool is surrounded by a cement walkway with a uniform width. The swimming pool
has a side length of (x – 3) feet. The side length of the entire square area including the pool and the
walkway is (x + 2) feet.
Enter an expression for the area of the walkway. Then find the area of the cement walkway when
X= 7 feet.
The area of the walkway is
ft?
When x = 7 feet, the area of the cement walkway is

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
