To solve the given expression, we can use the distributive property of multiplication over addition/subtraction.
First, we distribute the -2 across the terms inside the parentheses:
(j + 2) - 2(3 - 9j)
= j + 2 - 2*3 + 2*9j
= j + 2 - 6 + 18j
Next, we combine like terms:
= (j + 18j) + (2 - 6)
= 19j - 4
Therefore, the correct answer is:
O 19j - 4
Subtract: (j + 2) - 2(3 - 9j) (1 point)
O 19j - 4
O 19j + 4
O - 17j - 4
O - 8j - 4
