Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. she decides to make the length of the run 20 feet. she writes and solves the equation 2l + 2w = 62 to find the width of the run. which statements are true of the solution?

"Answer are:

A false (w is 11)  

B false (it won't be a rectangle if there is no width - it'll be a line - but the equation would not work)  

C True (must be a positive number)  

D True (you put the value of l in to find w)  

E True (you deduct the lengths from 62 to find w)  

The value of w cannot be a negative number.  

Substitution is used to replace the variable l with a value of 20.  

2L + 2W = 62  

L + W = 31  

W = 31-L  

W = 31-20 = 11

the answer is 31.27mph

900 degrees
