In the right triangle shown, the third side can be represented by the expression
Westkost [7]

The third side can be represented by D) x = \sqrt{z^{2} } -y^{2} .

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

In the given triangle, the hypotenuse is the side that is represented by z. Another side on the triangle is represented by the value y.

Step 2:

Assume the other side of the triangle measures x units.

So according to the Pythagorean theorem,

z^{2}  = x^{2} +y^{2} , x^{2} = z^{2} - y^{2} .

x = \sqrt{z^{2} } -y^{2} which is option D.

You are making several purchases from the b-better electronics store. You can buy from this store online or in a physical store.
alexandr402 [8]

Answer:

Online Ordering is better.

Step-by-step explanation:

So you now that you save 20% if you to physical store and you save $20 if you go to the online store.

Say you are spending 100 dollars at the store to make it easy. 20% of one hundred is $20 so that is the same amount of money.

Now let’s look at the taxes and shipping so at the physical store you have to pay taxes no matter what but online you only do it if you purchase is less than $75 and we have $80 ($100–$20=$80) so at the physical store you have some amount of Mandy that is more than $80 because of taxes but if you buy online it will be exactly $80.

-15 + 12x = 5x + 7 -3x<br> SOLVE FOR X
Natali [406]

Answer: x=\frac{11}{5}

<u>Simplify both sides of the equation</u>

<u></u>-15+12x=5x+7+-3x<u></u>

<u></u>12x-15=(5x+-3x)+(7) (Combine Like Terms)

12x-15=2x+7

<u>Subtract 2x from both sides</u>

<u></u>12x-15-2x=2x+7-2x\\10x-15=7<u></u>

<u></u>

<u>Divide both sides by 10</u>

<u></u>\frac{10x}{10} =\frac{22}{10}<u></u>

<u></u>x=\frac{11}{5}<u></u>

<u></u>
