Answer:

i hope this helps

Step-by-step explanation:

2x^{2} -16=0

+16        +16

2x^{2} =16

÷2    ÷2

x^{2} = 8

\sqrt{x^{2} }= \sqrt{8}

x= \sqrt{8}

-5x^{2} +9=0

-9          -9

-5x^{2}=-9

÷-5   ÷-5

x^{2} =1.8

\sqrt{x^{2} }= \sqrt{1.8}

x= \sqrt{1.8}

6x^{2} -15=27

+15        +15

6x^{2} =42

÷6   ÷6

x^{2} =7

\sqrt{x^{2} }= \sqrt{7}

x=\sqrt{7}

What's the answer?????????????
Taya2010 [7]

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)
