Question

Which of the following equivalent to the expression below? -6(1+7i)

Answer 1

The expression is given to be:

$-6\left(1+7i\right)$

Apply the distributive rule:

$a\left(b+c\right)=ab+ac$

Therefore, we have:

$=-6\cdot \:1-6\cdot \:7i$

Simplifying, the answer is gotten to be:

$=-6-42i$

OPTION D is the correct option.
