Answer:
6
Step-by-step explanation:
The rational root theorem states that the roots must be factors of p/q
where p is the constant and q is the coefficient of the highest order term
p = 8 which has factors ±1, ±2,±4,±8
q = 1 which has factors ±1
The possible roots are ±1, ±2,±4,±8
--------------------
±1
which simplifies to
±1, ±2,±4,±8
6 is not a possible root
Answer:
2 / 13
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of 4's = 4 ( 1 for each suit)
Number of 6's = 4 (1 for each suit)
Probability, P = required outcome / Total possible outcomes
P(a 4) = 4 / 52 = 1/ 13
P(a 6) = 4 /52 = 1/13
Probability of either a 4 or a 6
P(a 4) + P(a 6)
1/13 + 1/13
= 2 / 13
65. change 11 5/6 to a mixed number:
71/6-17/18
multiply 6 and 71 by 3 which equals 18 so now the denominators are the same
213/18-17/18=196/18
to simplify divide 196 and 18 by 2
196÷2=98
18÷2=9
now divide 98 by 9
98÷9=10 (rounded to whole number)
9×10=90
so to get 98 you add 8
your answer is 10 8/9
66. change both fractions to a mixed number
9 5/9=86/9
8 1/6=49/6
multiply 86 and 9 by 2
86×2=172
9×2=18
multiply 49 and 6 by 3
49×3=147
6×3=18
now subtract :
172/18-147/18=25/18
divide 25 by 18
25÷18=1 (rounded whole number)
18×1=18
to get 25 you add 7
your answer is 1 7/18
hope this helped
