Answer:
Step-by-step explanation:
(Assuming the den is a rectangle)
Let 
be the length of the den. Because the length is 10 feet longer than the width, the width of the den can be represented as 
.
The area of a rectangle is given as 
, therefore we can form the following equation:
Expanding this, we have:
This factors into 
, therefore 
.
Because -11 is extraneous, the length of the den is 
feet and the width is 
. Thus, the dimensions of the den are 
.
Answer:
C
Step-by-step explanation:
solve the equation in form of x
