Answer:
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? Check all that apply. The value of w is 10 feet. The value of w can be zero. The value of w cannot be a negative number. Substitution is used to replace the variable l with a value of 20. The subtraction property of equality is used to isolate the term with the variable w.
