Use the Pythagorean theorem:

c - a hypotenuse
a, b - legs
We have: a = 9 and c = 12. Substitute:

<em>subtract 81 from both sides</em>

A Pythagorean triple consists of three positive integers a, b and c, such that
.
is not positive integer.
<h3>The sides of the triangle do not form a pythagorean triple.</h3>
Step-by-step explanation:
sum was the first name of integral
and the median is something in the middle
for example :
A . B . C
the median is B
X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
Their all snakes? i dont what else there is to think of
Perimeter of rectangle = 2(l+w)
let. width = x, length = x+12
So, 100 = 2(x+x+12)
100=2(2x+12)
100=4x+24
4x=76
x=19, y=19+12 = 31
So, Length = 31 m & Width = 19 m
