D)
Because Mexico borders the US, but it does not border Canada. The conditional is false.
In the complex plane, this polynomial has three roots, exactly as its degree is.
Hope this helps.
Divide 20 by 4=5
then 5 by 7=5/7
k=5/7
Answer:
a) 336
b)6
c)6
Step-by-step explanation:
a) In the 1st place fit 8 cars, in the 2nd only fit 7 cars, because one is already in the first place and 3th fit 6 cars, so all the possibilities are 8*7*6.
b) in the 1st place fit 3 cars, 2nd 2 cars and 3th 1 car, so all the possibilities are 3*2*1
c) every shirt can be matched with 1 pair of pants, there are 2 shirts and 3 pants, so all the the possibilities are 6+6.
Step-by-step explanation:
o - odd number
e - even number
n + e =o, if n is odd...rule 1
n + e = e, if n is even...rule 2
n × o = o, if n is odd...rule 3
n × o = e, if n is even...rule 4
thus if 3n +6 = o,
then 3n must be odd, following rule 1
=> 3n = o, then n is an odd number, following rule 3
