Answer:
There is a mistake in Step 2. Maya distributed 3(x-10) as 3x+30, which is false. The correct step is: 6x+12 = 3x-30
Then solve for x
The answer is B. Maya made a mistake between Step 1 and Step 2 because she did not correctly distribute 3 to (x-10).
10 squared plus 18 squared equals C squared is the set up
After solving you should get 20.59
i think it’s 390,625 but a calculator can probably do this faster
