Answer: With the distributive property you get 72j+18+9j, with the addition property you get 9(9j+2)

Step-by-step explanation: The first way to do this is to distribute the nine among the numbers in the parentheses. Nine into 8j equals 72j. Nine into 2 equals 18. 9 into j equals 9j. Then the problem would be 72j+18+9j. The next answer would be to use the addition property. 8j+j equals 9j. Then there would be the 2, so you would have 9(9j+2)
