Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1

Answer:
61
Step-by-step explanation:
to calculate the 20th term you use the formula
Tn=a+(n-1)d where a stands for the first term,n the number of terms and d the common difference.in this case the first term is 4 the common difference is 3 cause they were adding 3 to go to the next term.. therefore the solution will be:
Tn=4+(20-1)3
=4+19×3
=4+57
=61
the 20th term is 61

Answer: D
Step-by-step explanation:
3(1+x)+7 = 3+3x+7 =3x+10
9+x / 3x = 5/6
If you look at it as a proportion, then you can "cross-multiply" it"
(9+x) · 6 = 3x · 5
54 + 6x = 15x
Subtract 6x from each side:
54 = 9x
Divide each side by 9 :
6 = x
