Answer:
Option c) 118 is correct
That is ![\sum_{n=5}^9 (3n+2)=118](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D5%7D%5E9%20%283n%2B2%29%3D118)
Step-by-step explanation:
Given problem can be written as
![\sum_{n=5}^9 (3n+2)](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D5%7D%5E9%20%283n%2B2%29)
To find the sum of the series:
First expand the given series
![\sum_{n=5}^9 (3n+2)=[3(5)+2]+[3(6)+5]+[3(7)+2]+[3(8)+2]+[3(9)+2]](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D5%7D%5E9%20%283n%2B2%29%3D%5B3%285%29%2B2%5D%2B%5B3%286%29%2B5%5D%2B%5B3%287%29%2B2%5D%2B%5B3%288%29%2B2%5D%2B%5B3%289%29%2B2%5D)
(adding the terms)
(adding the terms)
![=118](https://tex.z-dn.net/?f=%3D118)
Therefore ![\sum_{n=5}^9 (3n+2)=118](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D5%7D%5E9%20%283n%2B2%29%3D118)
Therefore option c) 118 is correct
That is ![\sum_{n=5}^9 (3n+2)=118](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D5%7D%5E9%20%283n%2B2%29%3D118)
The evaluated sum is 118.
The answer would be 12 just adding 3
Answer:
Width is 10 Length is 20
Step-by-step explanation:
Perimeter = 60
Length = W + 10
P = 2L + 2W Write the equation for perimeter
60 = 2(W + 10) + 2W Substitute your variables
60 = 4W + 20
- 20 - 20 Subtract 20 from both sides
40 = 4W Divide both sides by 4
10 = W
Answer:
4
Step-by-step explanation:
<em>4 is the rate because if she can make 4 in 10 min the the constant would be 4. By the way this didnt get answered becasue it was posted in spanish!</em>
