Answer:

The answer to your question is letter C. 7y³ + 7n²y² - 22y²

Step-by-step explanation:

y²(4y + 7n² + 2) - 3y² (-y + 8)

Multiply

4y³ + 7n²y² + 2y² + 3y³ - 24y²

Use the associative property for like terms

(4y³ + 3y³) + (2y² - 24y²) + 7n²y²

Simplify like terms

7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²

How is the sum expressed in sigma notation? 11 + 17 + 23 + 29 + 35 + 41

Advocard [28]

Answer:

The given sums 11+17+23+29+35+41 can be written as in sigma notation is $\sum\limits_{i=1}^{6}5+6i$

Therefore 11+17+23+29+35+41= $\sum\limits_{i=1}^{6}5+6i$

Step-by-step explanation:

Given series is 11+17+23+29+35+41

To find the given sum expressed in sigma notation :

11+17+23+29+35+41 can be written as the given sums in sigma notation is $\sum\limits_{i=1}^{6}5+6i$

That is

11+17+23+29+35+41= $\sum\limits_{i=1}^{6}5+6i$

Now expand the sums and to verify that whether the summation is true or not :

$\sum\limits_{i=1}^{6}5+6i=(5+6(1))+(5+6(2))+(5+6(3))+(5+6(4))+(5+6(5))+(5+6(6))$

$=(5+6)+(5+12)+(5+18)+(5+24)+(5+30)+(5+36)$

$=11+17+23+29+35+41$

Therefore 11+17+23+29+35+41= $\sum\limits_{i=1}^{6}5+6i$
