But ya got it wrong. Originally when this puzzle became known rule was “can’t cross lines”

2 4 8 12 24? 1/12 = 2/24 1/24 + 2/24 = 3/24 = 1/8 1/2 + 1/4 + 1/8 + 1/8 = 1

3, 4, 5, 6, 20 (1/3) + (1/6) = (1/2) (1/4) + (1/5) + (1/20) = (1/2) (1/2) + (1/2) = 1

Man, I haven't seen this one since I was in 4th grade. Spoilers below for the solution if you don't want to watch the video. The magic number is 15. Put 5 in the middle square. This will make middle horizontal correct; 9+5+1=15. Put the 3 above the 5. This will make the middle vertical correct; 3+5+7=15. Put the 4 above the 9. This will make the top horizontal correct; 4+3+8=15. Put the 2 below the 9. This will make the left vertical correct; 4+9+2=15. It will also make the forward-slash diagonal correct; 2+5+8=15. Finally, put the 6 below the 1. This will make the remaining directions correct. Right vertical; 8+1+6=15. Bottom horizontal; 2+7+6=15. Back-slash diagonal; 4+5+6=15.

If A-C=9 and A can not be 9 then C=A+1….. same page so far. From there, (B-1)-A=3 or B=A+4 Finally, A+(A+1)+(A+4)=8 or 3A=3, A=1 B=1+4 C=1+1 Little less math, just as fun

what ???? When you have 4 minutes on top of the big one, start timing , when all the sand is down, flip the big one and you have the additional 11 minutes. very simple puzzle

Sweet! I solved it a different way using trig, actually. After working out side length x, I used those measurements to work out the angles of the triangle. The one of importance was the one you marked down, which came out to about 26.565 degrees (arcsin(5/5sqrt5)). Now since the bigger triangle is proportional we can work out that side length by 15cos(26.565), which was about 13.416. Square that and then we have our answer of 180! Might've been unnecessarily complicated and required a calculator, but it still got the work done! Honestly, I dunno why I didn't just do the proportions. I think I just really like trig lol

To see de bonus coz l c u r de hero wen comes to bounus😂

Where can l see the date of this video CZ l want to follow this video according to the date please

❤ u know how to make a bonus l see congratulations but my Problem l don't know how to follow the date l just opened any videos like today l want a video for 31july 2024 notify me please

You can do a little preanalysis to narrow down the field. So 1+27=28, units digit is 8. 153, units digit is 3. So what number added to 8 gives either a 3 (nothing) or 13 (5).. So x^3 must have a units digit 5. At this point, it leaves only 5, which just happens to be the answer. No range-testing necessary, just verification of the result. That only really works if you know the result *is* a NN, not "can you find a digit that would make the result a NN?", because in that case you'd still have to try/test all digits that would fit the range.

Bro can i email a reasoning question long multiplication method??? Please provide email

Wow 😳😳❤

Look like mathematics education 😮😊❤

sq of 10.25 + sq 45 + sq 101.25 = rt of 405

12+24=36 😔

5x8 = 40 for the rectangle and triangle it is 36

I thought it was 76 how come ?

12x2 =24

I did the math so weird, i already knew the top purple was 4x4, then i used that to fugue it the yellow, 2x4, and used that to figure out the green was 6x4, then just added the widths to figure out the blue. So 4+4=8, then used the yellow to figure out it was 8x2, i got so lost after that. But yeah, how was i still correct with the numbers?

X is 25.

What is the point of this? The pics are literally unreadable they are so blurry.

The How and Why of Mathematics channel has a great video on why PEMDAS is wrong. th-cam.com/video/lLCDca6dYpA/w-d-xo.html

Really Easy

I am sorry.

Not that level to be called impossible.

7458?

Zero. The points are not linearly placed and so there exist no possible line segments that would connect every point.

i immediately thought of 6+5+4+3+2+1 :/ i guess im kinda right?

or just think that point A has 6 possible connections and B has 5 remaining unique connections and so on so the answer is 6+5+4+3+2+1 which im surprised you didn't mention because it feels like the most intuitive way to solve it and works even if you move the dots around or add more dots.

Easier if you skip that first step: 6+5+4+3+2+1 (6+1)+(5+2)+(4+3) 7*3 21

31680

also the word "triangle" = 39

How about giving me a shout out for providing the correct answer?

Dude. Your killing me

Thank you so much! I am using my mother’s account (her profile picture is a photograph of my baby brother) because my older sister is using my device. This helped me so much!

3!+(3!/3)=6+(6/3)=6+(2)=8

Let a = width of blue triangle It is given that the hypotenuse of the blue triangle is perpendicular to the hypotenuse of the green triangle. As such, we know that the gradients (slopes) of the two lines are negative reciprocals, so they multiply to -1: (-6/a)*(4/(11-a))=-1 -24/(11a-a²)=-1 24/(11a-a²)=1 24=11a-a² a²-11a+24=0 Then we solve for a value of a. Of the two values, 8 and 3, We choose the bigger one. We then use the Pythagorean triples (3,4,5) and (6,8,10) (a multiple of 345) to find the two sides of the rectangle, 5 and 10. Hence the area is 50.

Thanks, it was so helpful ❤❤❤❤❤

Thanks 🎉 it was so helpful ❤❤

X=8 provides a valid solution. While it may not identify with the depiction it meets all the requirements of the depiction. So Area can be = 60 also.
