Answer:
Option (d) is correct.
6 + 9 + 12 +15 = 
Step-by-step explanation:
Consider the given series expansion 6 + 9 + 12 +15.
since we have to write in series form of 3.
We first write each term of given series in term of 3k or 3k+3
6 can be written as 3(2) or 3(1)+3
9 can be written as 3(3) or 3(2)+3
12 can be written as 3(4) or 3(3)+3
15 can be written as 3(5) or 3(4)+3
Thus, we can write the given series as ,
or
Since, we have options to choose.
From the given option (d) matches our result.
So, 6 + 9 + 12 +15 =
A) La distancia del Sol a Neptuno en notación científica es 45 x 10^8 km.
B) Júpiter se encuentra a 930.000.000 kilómetros del Sol.
C) La distancia del Sol a Neptuno es 30 veces mayor que la que hay a la Tierra.
Dado que la distancia entre la tierra y el sol es de 1,5 . 10˄8 km, la distancia entre la Tierra y Júpiter es de 9,3 . 10˄8 km y Neptuno está situado a 4.500.000.000 Km del Sol, para determinar:
A) Expresa en notación científica la distancia del sol a Neptuno
B) Calcula la distancia a la que está situado Júpiter respecto al Sol
C) Calcula cuantas veces es mayor la distancia del Sol a Neptuno que la que hay a la Tierra.
Deben realizarse los siguientes cálculos:
- A) 4.500.000.000 = 45 x 100.000.000
- 100.000.000 = 10^8
- 4.500.000 = 45 x 10^8
- B) 9.3 x 10^8 = X
- 100.000.000 = 10^8
- 9.3 x 100.000.000 = X
- 930.000.000 = X
-
C) Tierra = 150.000.000
- Neptuno = 4.500.000.000
- 150 = 1
- 4.500 = X
- 4500 / 150 = X
- 30 = X

The next three terms are: -3, 6, and 15
To get each new term, we simply add 9 to the last term. So we add 9 to -12 to get -3. Then we add 9 to -3 to get 6. Finally we add 9 to 6 to get 15
In other words,
first term = -12
second term = first term+9 = -12+9 = -3
third term = second term + 9 = -3+9 = 6
fourth term = third term + 9 = 6+9 = 15
This process repeats forever though we only need three terms in this case.
So that's why the answer is the three values -3, 6 and 15
Answer:
Step-by-step explanation:
7. 6 + 1/2 + 1/2 = 7
8. shade it
9. 1.3 + 0.2 + 0.4 = 1.9 0.8 + 0.2 + 0.7 = 1.7
10. (2)(4)(5) = 40
(4)(5)(1) = 20
(5)(6)(0) = 0
hope dis helps ^-^
Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5
