19 j plus 4
−17j−4
negative 17 j minus 4
−8j−4
negative 8 j minus 4
To subtract (j+2)−2(3−9j), we need to distribute the 2 to both terms inside the parentheses:
(j + 2) - 2(3 - 9j)
= j + 2 - 2*3 + 2*9j
= j + 2 - 6 + 18j
Combining like terms, we have:
= j + 18j + 2 - 6
= 19j - 4
Therefore, the correct response is "19j - 4".
