Explanation:
First we expand the bracket 8 (t + 8)
This gives us 8t + 64
Option 1:
8t + 16 is not an option, so it goes in the neither box.
Option 2:
8t + 64 is an option, so it goes in the 8 (t + 8) box.
Option 3:
(8 * t) + (8 * 8) is an option, so it goes in the 8 (t + 8) box.
Option 4:
4t + 8 + 4t is an option, so it goes in the 8t + 8 box.
Option 5:
4 (2t + 2) is an option, so it goes in the 8t + 8 box.
Option 6:
(8 * t) - (8 * 8) is not an option, so it goes in the neither box.
