I did the work for it and I got an area of 136, sorry I don't think I got it.. thought that if I told you before I left you wouldn't pin it to yourself wondering why I just left.. again, my apologies. hope you get the correct answer! :(
Step-by-step explanation: Divide by -1 then add 8 to both sides and get (x+9)^3=-512, and the cube root of -512 is -8, so x+9=-8, and subtracting 9 from both sides we get x=-17 as answer.
