Remove unnecessary parenthesis, and combine like terms
(3+i) + (5-2i)
3+i + 5-2i
8+i
you added 3+5 which is 5 and i-2i which is "i"
hope this helps.
It would split up in eighths. So it would be like 1/8, 2/8, 3/8 ....
I would say Korey because let’s say you have a rectangle and two sides are 2 and the other two sides are 5. Well if you add 5 + 2 which equals 7 times 2 equals 14, you get the same answer as you would if you added everything
5/12 is the answer just do 15 and then add 15 + 21 to get 36 and then you reduce 15/36 and get 5/12
7(3r - 4)= 21r - 28 the answer to the question
