I think it is 256 you take3×-23 you get 20× then you minus the 2 and to end up with 18 then you times it by 3 and you and up with 72×

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
