Type the correct answer in each box. Use sigma notation to represent the following series for the first 10 terms. 3 + (-6) + 12

klemol [59]

Answer:

Kindly check attached picture

Step-by-step explanation:

Given the following :

First term (a) = 3

Second term = - 6

third term = 12

Fourth term = - 24

We can obtain the common ratio of the series using the relation :

(2nd term/ 1st term) = (3rd term/2nd term) = (4th term/ 3rd term) =....

(-6/3) = (12/-6) = (-24/12)

-2 = - 2 = - 2

$\dfrac{n^2+3n+2}{n^2+6n+8}-\dfrac{2n}{n+4}\\\\=\dfrac{n^2+2n+n+2}{n^2+4n+2n+8}-\dfrac{2n}{n+4}\\\\=\dfrac{n(n+2)+1(n+2)}{n(n+4)+2(n+4)}-\dfrac{2n}{n+4}\\\\=\dfrac{(n+2)(n+1)}{(n+2)(n+4)}-\dfrac{2n}{n+4}\\\\=\dfrac{n+1}{n+4}-\dfrac{2n}{n+4}=\dfrac{n+1-2n}{n+4}=\dfrac{1-n}{n+4}$

Please help with Geometry homework!!! Will give brainliest and 50 points to whoever answers first!!!

Answer:

x = 42.5

Step-by-step explanation:

It is said:

If two angles are not corresponding, then they make up 180°. They are more known as supplementary angles.

So the equation is:

a + b = 180°

Substitute

x + 8 + 3 x + 2 = 180°

x + 3x + 8 + 2 = 180°

4x + 10° = 180°

4x = 180° - 10°

4x = 170°

x = 170° ÷ 4

x = 42.5
