Answer:

62i + -21j

Step-by-step explanation:

Since d = -1/3i + 5/2j and c = 10i - j. We can plug these values into the expression, and we get -2(3(-1/3i + 5/2j) - 3(10i - j)). Simplifying this, we get -2(-i + 15/2j - 30i + 3j). We simplify this even more and we get -2(-31i + 21/2j). Finally, we multiply this out and get (62i)  + (-21j) as our answer.
