Answer:
28: 30p-10
30: -2-12d
32: 56a+32b
34: 6a-12b+18
36: -16+8g+8h
Step-by-step explanation:
for example:
2x(4+3)
You times both numbers by 2x
2x*4 = 8x
2x*3 = 6x
8x + 6x
Another useful fact is that a plus and a minus together (e.g 4+-5) is the same as just minus (4-5) and a minus next to a minus is that same as a plus (e.g 3--3 = 3+3)
Hope this helps! :D
