(-6 - 5i)(1 - 3i)
you foil this like you would any other set of binomials, so you'll multiply negative 6 and 1, then -5i and 1, etc:
-6 - 5i + 9i - 15
5i and 3i simplify to -15 because 5*3 is 15, and i*i = -1
then you just add like terms:
-21 - 5i + 9i
-21 + 4i is your answer.
Answer:
c: w < 2
Step-by-step explanation:
first move the left w to the left side of the equation which becomes -5w -7 > 3
and then move -7 to the right side of the equation. -5w> -10 and then divide -10 by -5 but since your dividing by a negative number u flip the sign and it becomes w < 2
Numbers expressed by exponents are powers
