Answer:
49, 49 , 98
Step-by-step explanation:
AC = AB + BC = 2AB
- 3x - 31 = 2(x+6)
- 3x - 31 = 2x + 12
- 3x - 2x = 12 +31
- x = 43
AB= BC = x + 6 = 43 + 6 = 49
AC = 2AB = 2* 49 = 98
Answer:
$9$
Step-by-step explanation:
Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.
To find: number that Thea originally entered
Solution:
The final number is $243$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $243$ must be $324$.
As previously the number was squared, so the number before $324$ must be $18$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $18$ must be $81$
As previously the number was squared, so the number before $81$ must be $9$.
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
Answer:
<h2>
![2 \sqrt{10}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B10%7D%20)
</h2>
Option C is the correct option.
Step-by-step explanation:
√ 8 • √ 5
Calculate the product
![= \sqrt{40}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B40%7D%20)
Simplify the radical expression
![= \sqrt{2 \times 2 \times 10}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B2%20%5Ctimes%202%20%5Ctimes%2010%7D%20)
![= 2 \sqrt{10}](https://tex.z-dn.net/?f=%20%3D%202%20%5Csqrt%7B10%7D%20)
Hope this helps...
Best regards!!
I believe the answer is 24 if not im sorry
