Use 2 mathematical properties to change 9(8j + 2 + j) into one expression (please show work)

Answer 1

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)

Answer 2

Original equation: 9(8j + 2 +j)

1st use Distributive property:

Multiply 9 by each term in the parenthesis:

72j + 18 + 9j

2nd use Addition Property to combine like terms:

81j +18
