Answer:

21. An= 100 (2)^n-1

22. $51,200

23. n= 15

Step-by-step explanation:

21. 100, 200, 400, 800, 1600...

An= A r ^n-1

22. a10= 100(2)^10-1

a10= 100(2)^9

23. n=14

a14= 100(2)^14-1= 819200

n= 15

a15= 100(2)^15-1= 1638400

Answer:

x=16/3=5.33.

Step-by-step explanation:

Isolate x on one side of the equation.

2+x3=18

2+x*3=18

2+x*3-2=18-2 (First, subtract 2 from both sides.)

18-2 (Solve.)

18-2=16

x*3=16

x*3/3=16/3 (Then, divide by 3 from both sides.)

16/3=5.33

x=16/3=5.33

In conclusion, the final answer is x=16/3=5.33.

Send it quick guys...
Paladinen [302]

Answer:

194

Step-by-step explanation:

Recall 2 rules to solve this easily:

1. (a+b)^2=a^2+2ab+b^2

2. (a-b)^2=a^2-2ab+b^2

<em>Now, if we let a = 7  and  b=4\sqrt{3}, we can say the problem is basically of the form:</em>

(a+b)^2 + (a-b)^2

This can be simplified using the rules:

(a+b)^2 + (a-b)^2\\a^2+2ab+b^2+a^2-2ab+b^2\\2a^2+2b^2

Now we can plug the values of a and b we initially thought of (remember though  \sqrt{x} \sqrt{x} =x):

2a^2+2b^2\\2(7)^2+2(4\sqrt{3})^2\\ 2(49)+2(4\sqrt{3})(4\sqrt{3})\\98+2(4)(4)(\sqrt{3} )(\sqrt{3} )\\98+2(4)(4)(3)\\98+96 \\194

194 is the final answer.
