For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

Which is the correct first step in finding the area of the base of a cylinder with a volume of 26x cubic meters and a height of 6.5 meters? v=bh 6.5=b(26x) v=bh v=26pi+(6.5) v=bh v=26pi(6.5) v=bh 26pi=b(6.5)

Solve the equation: x - 9 = -6 + 5 a. 21 b. 7 c. 14 d. 2
