Answer:
<h2>
(A.C.) 54 - 36 = m</h2>
Step-by-step explanation:
36 + m = 54 <em>subtract 36 from both sides</em>
36 - 36 + m = 54 - 36
m = 54 - 36
m = 18
The length is 12, because if it's 9 inches wide it has two sides of 9 inches which is 18. Then subtract that from the intial value 42 to get 24. After, you divide 24 by 2 due to there being 2 sides of the box and 24 is the sum of both sides. Hopethis helps!
