Find the length of the third side. If necessary, write in simplistic radical form.

____ [38]

Answer:

7

Step-by-step explanation:

Just use the Pythagorean Theorem ( $a^{2}$ + $b^{2}$ = $c^{2}$ )

Let a be the missing side

$a^{2}$ = $8^{2}$ - $\sqrt{15} ^{2}$

$a^{2}$ = $64$ - $15$

$a^{2}$ = $49$

Take the square root of each side

$a$ = $\sqrt{49}$

$a$ = $7$

So the missing side is 7.

Hope this helps! :)

Help plsssssss WILL GIVE BRAINLIEST

ruslelena [56]

Answer: (1,2)

Step-by-step explanation:

I will help you..

Given:

$-2x-5y=-12\\10x-4y=2$

Lets cancel out the x term..

$5(-2x-5y)=-12(5)\\=-10x-25y=-60$

Now our system looks like this:

$-10x-25y=-60\\10x-4y=2$

Add.

$-29y=-58\\y=2$

plug in 2 for y

$-2x-5(2)=-12\\-2x-10=-12\\-2x=-2\\x=1$

Therefore the system is:

$(1, 2)$

If this helped consider marking brainiest.

What is the solution to the equation below?<br><br>√2x/√x-1=2 <br><br>A. 4 B. 2 C. 5 D.3 <br>

nikdorinn [45]

Given:

The given equation is:

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

To find:

The solution for the given equation.

Solution:

We have,

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

On simplification, we get

$\sqrt{2x}=2\sqrt{x-1}$

Squaring both sides, we get

$2x=4(x-1)$

$2x=4x-4$

$2x-4x=-4$

$-2x=-4$

Divide both sides by -2.

$x=\dfrac{-4}{-2}$

$x=2$

Therefore, the correct option is B.
