Answer is c.
t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h
Answer:
42 feet
Step-by-step explanation:
the answer to your equation is 25, because 17 if 68 is 25
F(x)=x^3-9x
and
g(x)=x^2-2x-3
so you just need to divide f(x) by g(x)
Therefore:
f(x)/g(x) = (x^3-9x) / (x^2-2x-3)
and of course you need to factor these two function to see if some factor would cancel another
x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
