Answer:

9√15·cis(19π/24)

Step-by-step explanation:

The magnitudes multiply and the angles add:

= ((3√3)(3√5))·cis(π/8 +2π/3)

= 9√15·cis(π(1/8 +2/3)) = 9√15·cis(π(3/24 +16/24))

= 9√15·cis(19π/24)

Which expression is equivalent to 1/3(12x+6x-21)

marin [14]

Answer:

$6x-7$

Step-by-step explanation:

$\frac{1}{3} (12x + 6x -21)$

break it into pieces

$\frac{1}{3}*12x = 4x$

$\frac{1}{3}*6x=2x$

$\frac{1}{3} *-21=-7$

put it all together

*since there's no negative in front of the other numbers except 7 they're positive so you add them*

$4x + 2x - 7$

simplify

$6x - 7$
