Answer:

-45j - 9k

Step-by-step explanation:

Multiply -9 and 5j first to get -45j

Multiply -9 and k to get -9k

Answer:

-45j-9k

Step-by-step explanation:

−9 (5j+k) =(−9⋅5j)+(−9⋅k)

So, add them to get −45j+(−9k)

This will also equal to = −45j−9k.

(That was just without parentheses)

Finally you get -45j-9k
