Answer:
i think it's this Bh(x) = (x + 1)(10x - 1)
Answer:

Step-by-step explanation:
So, the 3 pairs of equal parts in ∆AOC and ∆BOD are:

Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).
I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18
9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)
factor 243 to find a perfect square
x = √(3*81)
x = 9√(3)<u />
You got this!!!! just don’t rush, if you really don’t know the answer, just chose letter C hahah :)
