Since the teachers at my daughter's school can't teach, I'm here to figure out how to explain it to her. very clear and easy to follow. thanks!

How did you get 13 on the first problem ?

[@anasmahmoud6186]

you use the pythagorean theorem formula. a squared + b squared = c squared

[@ashleycalderon2646]

MarsOnfire Lin no you’d get 13 please re check , I was also confused but gave the Pythagorean Theron a chance and got 13

[@invisibilius1978]

[@MdJitu-w5y]

Veryy Thank you sirrr the video is verryyy useful 🤗

[@blazeridhz548]

in 3:56 how is the hypotenuse 13, do we have to figure it out or is it the question

[@devondominique1140]

how do you know that the other side of the triangle is 13 in the first triangle and 17 in the second?

[@Tres-K-47]

He used Pythagoreans theory a^2+b^2=c^2 so 12 times twelve is 144 and 5 times 5 is 25. 25+144= 169. The square root of 169 is 13

[@Tres-K-47]

If you need more help with the concept watch a video on Pythagorean theorem

[@Futile-l6o]

@@Tres-K-47 The correct formula is actually: c= √a^2+b^2

I have assignment now, in first example you have - 5 and 12 and after you draw, and you put 13 in R, my question is how you find the 13?

[@christinekateregalario2224]

R=√(-5)²+(12)²=13 You just need to square the given two points. You're welcome!🥰

it's the hypotneuse

how would you graph a negative square root

I’m confused, where does 13 come from?

Pythagorean Theorem, 5 squared plus 12 squared = c squared

[@shellarosales6284]

Do I still need to simplify its both numerator and denominator have common difference ?

[@sylviasolis4324]

what doi do if its something like (-4,0) would that just make it undefined or do I use the 0 in the 6?

my professor is fine but growing up homeschooled i think i got so used to doing math either one on one, with youtube, or with a very small group, so i feel like we go through topics so quickly and topics like math just stick better like this, well technically best with one on one, but yeah.
