Thank you
I appreciate the post bro need tk study early for 10th grade
Thank you very much😭🫶🏻, I've been struggling at geometry
Because I have a test tmr
How’s it go
Than you your idea❤
Such a good video, thank you so much!
anyone know y=x^2 and y=-x^2+4, i thought when we reverse the sign of x it reflects in y-axis , but why this graph is reflecting in x-axis?
Thank you
This was extremely helpful
Let's hope I don't fail my test 🙏
youre fr a lofe saver
Thank you!
THANKS SO MUCH!!
thanks !
You have no idea how much your math videos help me
10 years later but helpful
pulling numbers out your ass
Bruh listen to the video
One way to find the distance between the points on number line is to count the number of units. Another quicker way is to take the difference of the absolute value.
Thanks in advance sir your presentation has been very helpful to me in deed
Bro thanks , I writing an Assignment and one Question all about Rhombus and your video is So help full to me Thanks ❤
Ty man, I appreciate it!🎉
👌👌👌👌👌👍👍👍👍👍👍
Could you tell as how do you get the last two angles on the last figure
Wow I got 20/20 thank u so much
u deserve a raise
Thank you, very helpful!
You are awesome, I’ve finally understood how to do this for my final!
Thanks a lot buddy

you literally just summed up 3 weeks of school, better than my teacher

@@meli.shenaniganswe are actually so lucky to have a genius teacher! Since he shows us what's the best possible way to solve this. He also does some shortcuts to make the lesson easier. A couple of students called him the magiciracle man😅
wow thx
what did you use for this?
HOLY SHIT THANK YOU
Thanks . saved my life
Great video. What is the software used to draw the prism?
How do you find the E if its not in the given?
Cried in a quiz because of this topic but I'm glad I came across this lesson, it helped me a lot to better understand it. Thank you
same bro felt like the biggest idiot LMFAOOO 😭😭
This helped me a lot, thank you 🙏
Thanks so much! I'm studying for a quiz about all of these things, thanks so?so much!
thanks so much for making it easy to understand, saved me on my hw
Why was 90 degree not cut in half?
Thank you when I tell you I was gonna give up you was my last hope on this thank you
For the last problem I solved it by doing GK^2 + JK^2 = JG^2 and got 25 + 25 = 50 because GK = 5 and all sides of a rhombus are equal and so JG would be the root of 50. But, the root of 50 / 2 doesn't equal 4 it equals about 3.54. Can someone tell me where I went wrong?
Thank you!
Thank you for teaching me i learned this weeks ago and i forgot it and i found your video it really helped and now passing geometry
Thank you for the table!!! I know I learned it couple years ago and forgot. Now I know it.
Point of inters ection from point to line
thank you!
why is my ti 84 only showing a single parabola for the function? even on standard window
At 4:20 why do you change the sign of 7 to plus 7?
i think it was a mistake because there shouldn't have been a reason to.
