Answer:

xyz=-3.11

Step-by-step explanation:

X+2x+8X-2y+6y-6y-2z-2z-14z=8+9+11

11x-8y+6y-18z=28

11x-2y-18z=28

xyz(11-2-18)=28

xyz(11-20)=28

xyz(-9)=28

xyz=28/-9

xyz=-3.11

Given z=4+3i evaluate z

DerKrebs [107]

Answer:

Step-by-step explanation:

Assuming we want to evaluate |z|, given that, z=4+3i.

Then, by definition of modulus,

$|x + yi| = \sqrt{ {x}^{2} + {y}^{2} }$

$|4+ 3i| = \sqrt{ {4}^{2} + {3}^{2} }$

$|4+ 3i| = \sqrt{ 16+ 9 } \\ |4+ 3i| = \sqrt{25 } \\ |4+ 3i| = 5$

Therefore the modulus be of the given complex number is 5 units
