PLS HELP WILL MARK BRAINLIEST expression 9(2j + 7 + 5j).

use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.

Answer
18j + 63 + 45j & 63j + 63

Explanation
What I did to solve this is you do 9 times 2j that will give you 18j then 9 times 7 that will give you 63 then 9 times 5 that will give you 45j. So your expression for that will be 18j + 63 + 45j. Now for the second expression what I did was I added that like terms 18j and 45j.
18j + 45j will give you an answer of 63j. Now the 63 you have because you multiplied 9 times 7, that stays the same, you don’t do anything to the 63. So your second expression will be 63j + 63.

Final
first expression= 18j + 63 + 45j
Second expression= 63j + 63

Hope this helped you understand!
Your welcome and have a blessed
day/night :)

I'm not sure exactly but my best guess would be 1/4
