Short Answer

Solve.
-Elissa wants to set up a rectangular dog run in her backyard. She has 36 feet of fencing to work with and wants to use it all. If the dog run is to be x feet long, express the area of the dog run as a
Function of x.
A) $A ( x ) = 17 x - x ^ { 2 }$
B) $A ( x ) = 18 x - x ^ { 2 }$
C) $A ( x ) = 19 x - x ^ { 2 }$
D) $A ( x ) = 20 x ^ { 2 } - x$

• A) \(A ( x ) = 17 x - x ^ { 2 }\)
• B) \(A ( x ) = 18 x - x ^ { 2 }\)
• C) \(A ( x ) = 19 x - x ^ { 2 }\)
• D) \(A ( x ) = 20 x ^ { 2 } - x\)
