Answer:
2x
Step-by-step explanation:
7x= 7*x
5x=5*x
Subtract.
7-5=2
2*x=2x
So 2x is the answer.
Given:
The given sum is:
![\sum _{k=4}^9(5k+3)](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29)
To find:
The expanded form and find the sum.
Solution:
We have,
![\sum _{k=4}^9(5k+3)](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29)
The expanded form of given sum is:
![\sum _{k=4}^9(5k+3)=(5(4)+3)+(5(5)+3)+(5(6)+3)+(5(7)+3)+(5(8)+3)+(5(9)+3)](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29%3D%285%284%29%2B3%29%2B%285%285%29%2B3%29%2B%285%286%29%2B3%29%2B%285%287%29%2B3%29%2B%285%288%29%2B3%29%2B%285%289%29%2B3%29)
![\sum _{k=4}^9(5k+3)=(20+3)+(25+3)+(30+3)+(35+3)+(4+3)+(45+3)](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29%3D%2820%2B3%29%2B%2825%2B3%29%2B%2830%2B3%29%2B%2835%2B3%29%2B%284%2B3%29%2B%2845%2B3%29)
![\sum _{k=4}^9(5k+3)=23+28+33+38+43+48](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29%3D23%2B28%2B33%2B38%2B43%2B48)
![\sum _{k=4}^9(5k+3)=213](https://tex.z-dn.net/?f=%5Csum%20_%7Bk%3D4%7D%5E9%285k%2B3%29%3D213)
Therefore, the correct option is C.
