Kelly wants to create a rectangular playpen for his cats in his backyard, and estimates that the cats will need 500 square feet. he also wants the length of the playpen to be 20 feet longer than the width, so they have room to run. what dimensions should the playpen be?

What about 135 ft. x 115 ft. ?

2(l+w) = 500

2(135+115) = 500

2(250) = 500

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
