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>
Answer: 
Step-by-step explanation:
Here the give expression is,

We can write,
( because
)

⇒ Option D is correct.
First, make sure you convert both equations into standard form. Your two equations would be 2x+2y=38 and -x+y=3. Then multiply the bottom by 2. So your new equations would be 2x+2y=38 and -2x+2y=6. The x would cancel out and you would continue solving for y. y would equal 11 and then you would plug it back into an original equation. When you plug and solve for x, you would get x=8. So your answer would be (8,11)
Answer: 12
Step-by-step explanation:
Answer:
never ever learned this but maybe The answer is:
b. y - 2 = 2/3(x-1)
c. y - 4 = 2/3(x-4)
e. f(x) = 2/3 + 4/3
