Answer:
Looks correct to me.
Step-by-step explanation:
(X + 4)(x - 1)(x -6) = (x^2 - x + 4x -4)(x - 6)
(x^2 + 3x -4)(x - 6) = x^3 -6x^2 + 3x^2 - 18x - 4x + 24 = x^3 - 3x^2 - 22x + 24
It is the first one
Y - 4 = 6 (x - 7) is the correct equation
The answer is 10 2/11. I hope this helps!
I suppose the two given numbers are the length of the two legs.
Pythagorean theorem: 385.7^2 + 321.84^2=hypotenuse^2
