52=3x
x=17.333
D
As likely as not. There are 26 red cards and 26 black cards, so there is a 50% chance of getting red and a 50% chance of getting black.
Answer:
B (2,-4)
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
measure of angle E: 5(6) + 8 = 38
measure of angle D: 6(6) + 8 = 44
measure of angle C: 180 - 82 = 98
check answers by adding all 3 angle measures to make sure they equal 180 degrees
Answer:
50 i - 41
Step-by-step explanation:
Simplify the following:
(-7 i + 8) (i - 6)
(8 - 7 i) (i - 6) = (8) (-6) + (8) (i) + (-7 i) (-6) + (-7 i) (i):
-6×8 + 8 i - 6 (-7 i) - 7 i×i
-6×8 = -48:
-48 + 8 i - 7 i (-6) - 7 i×i
-7 (-6) = 42:
-48 + 8 i + 42 i - 7 i×i
-7 i×i = -7 i^2:
-48 + 8 i + 42 i + -7 i^2
i^2 = -1:
-48 + 8 i + 42 i - 7-1
-7 (-1) = 7:
-48 + 8 i + 42 i + 7
-48 + 8 i + 42 i + 7 = (8 i + 42 i) + (7 - 48) = -41 + 50 i:
Answer: 50 i - 41
