Answer:
Check boxes 3,4, and 5
Explanation:
It is given in the problem that the equation to find the width of the run is 2l+2w=62 and l=20 feet
You can plug in 20 for l in the previous equation by using Substitution. It should look like this:
2(20)+2w=62
Next multiply 2 by 20 to get 40:
40+2w=62
Then subtract 40 from both sides: (Subtraction property of equality)
2w=22
Then divide 2 from w AND 22:
w=11
This means that the first box is INCORRECT as the width was calculated to be 11 not 10.
The width cannot be a negative number or 0
