I have a right triangle I have to find the area for
On the figure they have points a b c
A to C 6ft C to B is 9ft and I must need A-B
the right triangle does show a 90 degree at point C
Simplify by dividing:
x^3+2x^2+3x-6/x-1
I don't understand why I can't do this, but I know once I see it I'll hopefully understand! :)
