Also please show work

Answer 1

Do you know Pythagorean?

Answer 2

Yes, a2+b2=c2

Answer 3

good

Answer 4

By Pythagorean, you have \( DC = AC^2 -AD^2\) , moreover, you still have \(DC^2=BC^2-BD^2\) right?
hence, \(AC^2-AD^2=BC^2-BD^2\), all have numbers, plug in and solve for x

Answer 5

sorry, the first one is DC^2 not DC

Answer 6

Okay so so far I have
\[10x-2^{2}-8x ^{2}=7x ^{2}-5x+3^{2}\]
Is that right so far?

Answer 7

Nope

Answer 8

\(AC^2=(10x-2)^2 = 100x^2-40x+2^2\) , the same for others, not as you stated.

Answer 9

Alright then what?

Answer 10

Plug all them in in CORRECT way first, then solve for x. I want to see your equation
