Answer:
6
Step-by-step explanation:
Try this option:
1. note, that the number 84 is divided by numbers: 1;2;3;4;6;7;12;14;21;28;42 and 84. It means, that measurements of the length may be: 1;2;3;4;6;7;12;14;21;28;42;84 and for the width: 84;42;28;21;14;12;7;6;4;3;2;1.
2. according the numbers calculated in item 1, the possible number measurements for the length and width of the sandbox are (length; width):
1;84
2;42
3;28
4;21
6;14
7;12
12;7
14;6
21;4
28;3
42;2
84;1
We know the answer is B, because we would need to divide the 20 by 4 and the 12 by 4 in order to see the equal amounts of balls each friend has.
The third table is the answer.
x=-5 => y=-5-6=-11
x=-8 => y=--8-6=-14
y=-7 => y=-7-6=-13
