a pythogorean is a set in integers \(a,b,c\) that solve \[a^2+b^2=c^2\]
if \(a\) is 7 and \(b\) is 24, what is \(c\)?
OpenStudy (anonymous):
would i add or muiltplay
OpenStudy (unklerhaukus):
square each of 7, and 24 , then add them
OpenStudy (unklerhaukus):
finally take the square root of this to get c
OpenStudy (anonymous):
so 49+576=625

OpenStudy (unklerhaukus):
so what is c?
OpenStudy (anonymous):
625 ?
OpenStudy (unklerhaukus):
625 is c^2
take the square root of 625 to get c ,
OpenStudy (anonymous):
25 !!!
OpenStudy (unklerhaukus):
yeahs

i have another question
OpenStudy (unklerhaukus):
what it is
OpenStudy (anonymous):
ok a square patio has an area of 50 square feet.to the nearest tenth of a foot what is the length of the patio
OpenStudy (unklerhaukus):
use The area of a square is equal to its side length squared
as an equation ,[ with the side length as \(s\) and the area as \(A\)]
\[A=s^2\]
if you take the square root of both sides
\[\sqrt A=s\]
OpenStudy (anonymous):
would u square 8

if the sides were 8
the are would be 8^2 = 64
which is too large
OpenStudy (unklerhaukus):
the area*
OpenStudy (unklerhaukus):
take the square root of fifty to find your side length
OpenStudy (unklerhaukus):
if the area was 49 , the sides would be √49 = 7. but this is a little bit too small
