Answer: Simplifying the expression of the substraction of the two complex numbers we get 11-2i
Solution:
(5-5i)-(-6-3i)
Eliminating the parentheses: 5-5i+6+3i
Grouping similar terms: (5+6)+(-5+3)i
Adding the similar terms: 11+(-2)i = 11-2i
The formula for volume of a sphere is 4/3(pi*radius³)
4/3*3.14*12³=7234.56 inches ³
6 1/3 - 4 2/3 is 1 2/3 so... 1 2/3 feet longer
