Answer:
The first one because it does not repeat the numbers
Step-by-step explanation:
The answer would be 901 because they said what is the least number they would need to read and their goal is MORE than 900. The amount of books that they already had is useless information (Ignore). They love giving trick questions. :)
1) (-4) + (-9) = -13
2) 5 + (-12) = -7
3) -6 + 5 = -1
4) -7 + 7 = 0
<span>5) -7 + 2 ___ 3 + (-9)
- 5 ____ - 6
</span>-7 + 2 > 3 + (-9)
6) <span>4 + (-8) ___ 6 + (-8) + (-6)
- 4 ____ - 8
</span><span>4 + (-8) > 6 + (-8) + (-6)
7) </span><span>$66
8) </span><span>-$12

You have the correct steps and final answer. The area of the room is 196 square feet, so each side is sqrt(196) = 14. The perimeter is 14*4 = 56 feet. You'll need 6 boards (each 10 ft long) to get 60 ft total. You'll have 60-56 = 4 ft of board left over. This is assuming that there isn't any other type of waste or mistakes made in cutting.
Nice work on getting the correct steps and final answer.
