B -13 -34i

(7 + 2i)(-3 - 4i)
Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)

Solve for k. k/2 +1/2=3

ikadub [295]

Answer:

$k = 5$

Step-by-step explanation:

Solve for $k$ :

$\frac{k}{2} + \frac{1}{2} = 3$

-Multiply both sides of the equation by the denominator $2$ :

$2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2$

$k + 1 = 6$

-Subtract both sides by $1$ :

$k + 1 - 1 = 6 - 1$

$k = 5$

So, the value of $k$ is $5$ .
