Answer:
3rd integer:n+2
Step-by-step explanation:
Kelly sells 52 subscriptions every 72 days, therefore,
216 / 72 = 3.
52 * 3 = 156
Kelly sells 156 subscriptions every 216 days
Answer/Step-by-step explanation:
1. (7j³ - 2) + (5j³ - j - 3)
Open the parentheses
7j³ - 2 + 5j³ - j - 3
Collect like terms. Like terms are terms that have the same degree.
7j³ + 5j³ - j - 2 - 3 (7j³ and 5j³, have the same degree, 2 and 3 are if the same degree)
12j³ - j - 5 (this already in descending order)
2. (8a⁵ - 4) + (3a⁵ + a - 2)
Open parentheses
8a⁵ - 4 + 3a⁵ + a - 2
Collect like terms
8a⁵ + 3a⁵ + a - 4 - 2
12a⁵ + a - 6 (in ascending order from largest to smallest degree)
3. (6m² + 1) + (3a⁵ + a - 2)
6m² + 1 + 3a⁵ + a - 2
Collect like terms
6m² + 3a⁵ + a + 1 - 2
6m² + 3a⁵ + a - 1
Rearrange from largest to smallest degree
3a⁵ + 6m² + a - 1
4. (3m⁵ + 1) + (9m⁵ + 3m - 2)
3m⁵ + 1 + 9m⁵ + 3m - 2
Collect like terms
3m⁵ + 9m⁵ + 3m + 1 - 2
12m⁵ + 3m - 1
5. (- 5x² - x + 4) + (- 3x² - 5x + 2)
Open parentheses
-5x² - x + 4 - 3x² - 5x + 2
Collect like terms
-5x² - 3x² - x - 5x + 4 + 2
-8x² - 6x + 6
Answer:
S infinity= -51/4
Step-by-step explanation:
First term
ar= -9
Fifth term
ar⁴= 1/3
Solving for the value of the r and a
ar= -9
ar⁴= 1/3
Dividing each other
r³=1/3 * -1/9
r³=-1/27
r= 3√-1/27
r= -1/3
Solving for a
ar= -9
a(-1/3)= 9
a= 9*-3
a= -27
Sum of a go to infinity is given by the formula
S infinity= a/(1-r)
S infinity= -27/(1-(-1/3))
S infinity= -27/(1+1/3)
S infinity= -27 * 3/4
S infinity= -51/4
