Answers

Answer 1

Answer: he spend: 1440*2.5=3600
he earn: 0.25*1440*12=4320
[because he sells 0.25/each and buy 1440 dozen so 1440*12]

4320-3600=720

5c+10=79

Please Simplify: 3+5i/2-i

Answers

ok so
(3+5i)/(2-i)
try to make it into the form a+bi
make bottom number in real
remember that i^2=-1 and
(a-b)(a+b)=a^2-b^2
look at bottomm
(2-i)
we can make it into 2^2-i^2 by multiplying it by (2+i)

multiply top and bottom
(3+5i)/(2-i) times (2+i)/(2+i)=(6+10i+3i+5i^2)/(2^2-i^2)= (6+13i+5(-1))/(4-(-1))=(6+13i-5)/(5)= (1+13i)/5=(1/5)+(13i/5)

a+bi
1/5+13/5i

Answers

First you need to subtract both numbers and then, add them up. You'll receive e.g. 6-4=2 and 6+4=10, then just type them one after another, which will give you 6+4=210.
