Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
we know that
In a right triangle
Applying the Pythagorean Theorem

where
a and b are the legs of the triangle
c is the hypotenuse of the triangle
Step N 
<u>Assume that the third side is a leg</u>
In this case we have


Solve for b

substitute the values



Step N 
<u>Assume that the third side is the hypotenuse</u>
In this case we have


substitute the values



Step N 
<u>Find the difference of the third sides</u>

therefore
<u>the answer is</u>

Answer:
D
Step-by-step explanation:
To find an equivalent ratio it must be multiplied or divided by the same number.
I multiplied 8 by 5 which got me 40
Then I multiplied 9 by 5 which got me 45
This means the equivalent ratio is 45/40
