Multiply the numbers like you multiply binomials.
Multiply every term of the first binomial by every term of the second binomial.
Then combine like terms, and remember that i^2 = -1.
(3 + 2i)(4 - i) =
= 12 - 3i + 8i - 2i^2
= 12 + 5i + 2
= 14 + 5i
Answer: -3
Step-by-step explanation:
Given
Equations of the lines are
For the system of linear equation has no solution if
Rewrite the equations
Insert the values for the no solution condition
Therefore, for c=-3, the system of linear equation ha no solution.
18 - [ 18 - [ 18 - ( 18 - 1)]]
= 18 - [ 18 - [ 18 - 17]]
=18 - [ 18 - 1]
= 18 -17
=1
You round up if the number is bigger then 5 and the number stays the same if it's smaller then 5
