What is a simplified expression for (x−y)−(x+y)?

stellarik [79]

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

The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length

andrew11 [14]

we know that

In a right triangle

Applying the Pythagorean Theorem

$c^{2} =a^{2} +b^{2}$

where

a and b are the legs of the triangle

c is the hypotenuse of the triangle

Step N $1$

<u>Assume that the third side is a leg</u>

In this case we have

$a=12\ in\\c=15\ in\\ b=?$

$c^{2} =a^{2} +b^{2}$

Solve for b

$b^{2}=c^{2} -a^{2}$

substitute the values

$b^{2}=15^{2}-12^{2}$

$b^{2}=81$

$b=9\ in$

Step N $2$

<u>Assume that the third side is the hypotenuse</u>

In this case we have

$a=12\ in\\b=15\ in\\ c=?$

$c^{2} =a^{2} +b^{2}$

substitute the values

$c^{2}=12^{2}+15^{2}$

$c^{2}=369$

$c=19.2\ in$

Step N $3$

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

$19.2\ in-9\ in=10.2\ in$

therefore

<u>the answer is</u>

$10.2\ in$

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
