A) $3.1 + 11.4 \mathrm { i }$
B) $3.1 - 11.4 \mathrm { i }$
C) $- 2.3 - 6 i$
D) $9.5 + 5 \mathrm { i }$

Question

Quizplus · Accepted Answer

To solve the given expression, combine like terms: real parts with real parts and imaginary parts with imaginary parts. $3.6 - 0.5i - (-5.9 - 5.5i) = 3.6 + 5.9 + (-0.5i + 5.5i) = 9.5 + 5i$.

Add or Subtract (3.6−0.5i)−(−5.9−5.5i)( 3.6 - 0.5 \mathrm { i } ) - ( - 5.9 - 5.5 \mathrm { i } )(3.6−0.5i)−(−5.9−5.5i)

Add or Subtract $( 3.6 - 0.5 \mathrm { i } ) - ( - 5.9 - 5.5 \mathrm { i } )$
