Question

Which of the following is equivalent to the expression below? 3(5-2i)A. 15-2iB. 15-6iC. 8-2iD. 8-5i

Answer 1

B. 15 - 6i

Explanation:

We have the following expression:

`3\left(5-2i\right)`

We apply the distributive property and we are left with the following:

`\begin{gathered} 3\left(5-2i\right)=3\cdot \:5-3\cdot \:2i \\ \\ 3\left(5-2i\right)=15-6i \end{gathered}`

Therefore, the correct answer is B. 15 - 6i
