If you were like me & had more important things to do, so couldn't follow all of @NASAArtemis II, or if you can't get enough of it: I created a #playlist in chronological order. Please let me know of further #videos. I'll also add new ones as I find them: https://t.co/7PRN2goUQT

@captainblack566 1453. Took me a second 🤷🏻‍♂️

@RHSTUDYZONE You can’t be serious 🤦🏻‍♂️

@HunterBiden @PatPear70769830 I agree it's not the fighters or even the UFC I take issue with it's the fact that an orange idiot has turned the Whitehouse into redneck CirqueDumbSoleil. I don't blame the fighters or UFC for doing what it does. I blame the person who let it happen on the Whitehouse fekn lawn.

[Hunter Biden @HunterBiden]

Dear Joe,
I wish I could sit down with you face to face and explain why so many of us were offended by the UFC fight on the South Lawn of the White House.
For me, it had nothing to do with the UFC or who showed up for the fights. The brand you and Dana have built is a bona fide American success story. More power to you. As for the fighters, in my book, anyone brave enough to put it all on the line in the arena is remarkable to witness. Their dedication and discipline inspire me. I don’t understand anyone who can’t admire that.
And as for the people who attended, I, for one, love Shane Gillis. I think he’s hilarious and brilliant. It was a show. A once-in-a-lifetime spectacle. I can’t blame anyone for wanting to witness it firsthand.
My problem is that I believe some of our public spaces are sacred. And unlike many of the great powers that came before us, these American monuments belong to all of us. Not to whoever happens to hold power at the moment.
The White House does not belong to Donald Trump. It does not belong to any President. It belongs to the people. To treat it as Caesar treated the Colosseum is antithetical to everything our founding fathers fought for.
This is not Rome. Presidents are not emperors doling out bread and circuses for the peasants. The White House is the People’s House. This “celebration” could have happened in any stadium within a stone’s throw of the South Lawn. No one would have had an issue with it.
But that was obviously Donald Trump’s whole point. By holding the event on the South Lawn, what he was saying to the rest of us is:
“This is my house. I own it. I will do with it what I please. I’ll build a colosseum and have the gladiators fight under my gaze. I’ll tear down the East Wing. I’ll pave over the Rose Garden. I’ll cover everything in gold and marble. I’ll erase the names of all the men who came before me.”
The fights were an exhibition of imperial domination, not a celebration of our 250th anniversary as a democracy.
The White House is not Buckingham Palace. It is not the Palace of Versailles. It is not the Forbidden City of Beijing. It does not belong to an emperor, or a king, or a commissar.
The White House belongs to us. All of us. The person who sits behind the Resolute Desk in the Oval Office is nothing more than an honored guest. A temporary caretaker.
The President is our servant. Not our Caesar.
Respectfully, Hunter

P.S. Cage match between me and Don Jr.? Your call on the venue. Anywhere but the South Lawn.

@Eva_flag m = 36. [11 + 3 − 8 = 6 = √(36).]

[Thomas Lahn @PointedEars2]

@SamadSpeak @farman4x 👨🏻‍🏫 Think about how you would undo taking the square root. Therefore, what must 3x + 1 be equal to? Then solve for x.

[Thomas Lahn @PointedEars2]

@farman4x x = 33 because 3x + 1 =ꜝ 100.

Ask something new 🥱

[Thomas Lahn @PointedEars2]

@proinexcel @zeng_2605 How? Mathematically this is nonsense. The notation requires an explanation by a definition.

[Thomas Lahn @PointedEars2]

@BholanathDutta The angle in the bottom center belongs to the left large triangle. Its size is

180° − 80° − 40° = 60°.

The wanted angle is an exterior angle of the top angle of the small triangle. Its size is the sum of the non-adjacent interior angles of that triangle:

70° + 60° = 130°.

[Thomas Lahn @PointedEars2]

@KayMart08727580 @proinexcel Ah, guessing is easy, but was it an *educated* guess? What was your rationale?

[Thomas Lahn @PointedEars2]

@bestmate183 @proinexcel Nicely done. This is basically an attempt (ISTM that it is not yet complete) at a formal proof for what I thought and wrote in words 🤓

[Thomas Lahn @PointedEars2]

@zeng_2605 @proinexcel While your result is correct, your solution does not look right. But perhaps you mean the right thing. Explain.

[Thomas Lahn @PointedEars2]

@proinexcel The only (decimal) possibility is A = 6 because there is no other integer from 0 to 9 inclusive which when multiplied by 3 has 8 as the digit of lowest value.

The other digits “fall in their place”:

6 + 6 + 6 = 3 × 6 = 1_8_
6 + 6 + 1 (from 18) = 1_3_
6 + 1 (from 13) = _7_.

[Thomas Lahn @PointedEars2]

@_Aria_2210 80 ÷ (1/2) + 40
= 80 × 2 + 40
= 160 + 40
= 200.

If this is “top of the class”, something is wrong with your class.

[Thomas Lahn @PointedEars2]

@Burhan_142005 @_isa_2210 @__Libra0 It cannot be more than 100 % correct.

[Thomas Lahn @PointedEars2]

@_isa_2210 @__Libra0 You are mistaken.

√(21 + 28) = √(49) = 7.

So x = 28 is a solution, and it is the _only_ solution.

In detail:

√(21 + x) = 7
⇔ 21 + x = 7² = 49
⇔ x = 49 − 21 = 28. ∎

[Thomas Lahn @PointedEars2]

@_isa_2210 The only solution is 7² − 21 = 49 − 21 = 28. It does not require a mathematician and takes longer to write than to guess/calculate in one’s head.

[Thomas Lahn @PointedEars2]

@Batmantallk Supplemental: The original equation already implies y ≠ 0, so IMHO this can be tacitly assumed here. The correct solution confirms it: y = 9 ≠ 0.

If y ≠ 0 is not implied, one has to watch for apparent solutions. It is good to test solutions, especially when there are roots.

[Thomas Lahn @PointedEars2]

@Batmantallk [√(64) + √(16)]/√y = 4
⇔ (8 + 4)/√y = 4
⇔ 12/√y = 4
⇔ √y = 12/4 = 3
⇔ y = 9.

Did you mean ”US Americans” by “people”? Because I can believe *that* 🥲

[Thomas Lahn @PointedEars2]

@_Aria_2210 @Batmantallk How did you get that idea? Serious question. (Because I cannot fathom how.)

[Thomas Lahn @PointedEars2]

@jd2O8KM0EP46504 @zakiaonsol @Batmantallk 12/3 = 3? 😉
