Question

I need help with a few questions about Pythagorean Inequalities? I will medal!

Answer 1

Do you know what \(2\sqrt{22}\) equals?

Answer 2

2 square root of 22?

Answer 3

If I knew what \(2\sqrt{22}\) equaled, I could help you, but I don't. :P

Answer 4

I typed it in the Calculator and it popped up 9.38

Answer 5

Same...

Answer 6

It just multiplies 2 x the square root of 22. Is that correct? @welshfella

Answer 7

if its a right angled triangle the (2 sqrt22)^2 will = 5^2 + 8^2

Answer 8

Yes, but does \(2\sqrt{22}\) equal about 9.38?

Answer 9

That's what my calculator is saying @AnswerMyQuestions

Answer 10

5^2 + 8^2 = 25 + 64 = 89

now you need to find out if QS = sqrt89

Answer 11

- if it is then by Pythagoras its a right angled triangle

Answer 12

Yes, It's B :) Thanks

Answer 13

That's what I thought...

Answer 14

I wish I could give more then one medal :(

Answer 15

best thing is to square 2 sqrt22 to see if is 89

Answer 16

@KrazyKricket You actually can.... >:)

Answer 17

How??

Answer 18

@KrazyKricket First, make sure you haven't gave anyone a medal(If you have, take it away). Then, open the same post in a new tab, so you have 2 of the same tabs open. Then you can give 2 people medals on the same post. :D

Answer 19

(2 sqrt22)^2 = 2^2 * (sqrt22)^2 = 4 * 22

Answer 20

Thanks :) Now you both have a medal!

Answer 21

:3

Answer 22

thats not 89 is it?

Answer 23

by definition of the square root:-
