Answer:

10 +8i

Step-by-step explanation:

You add these the same way you would if they were considered to be polynomials.

Simora [160]

Answer:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

Step-by-step explanation:

Taking the succession:

$1+r+r^{2}+r^{3}+.....+r^{n-1}$

You can multiply and divide by 1-r without chaging the result:

$\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})$

Distributing the upper part of the fraction you have:

$\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})$

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only $(1-r^{n})$ will be left so:

$1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}$

Geometry question number 21

Pie

Step-by-step explanation:

1st) Distribute 8 with x and 8 with -1 which will give you

8x-8=5x-35

2nd) Use opposite operation and add 8 both sides

8x-8=5x-35

+8 +8

---------------

8x=5x-27

3rd) subtract 5x from both sides

8x=5x-27

-5x= -5x

_______

3x=-27

4th) Divide 3 from both sides so -27 by 3

3x=-27
