In AABC, AC is extended through point C to point D, mZBCD = (9x – 1)", m ABC = (3x + 18)", and mZCAB = (3x – 4)º. Find mZCAB.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

I'm not sure sorry that i couldn't
