The GCF is 6t3
3
3t
9t=702 t=702/9 t=78
9t + 9 = 9 (t + 1)
9t = 4t + 120 9t-4t = 4t - 4t + 120 5t = 120 5t/5 = 120/5 t = 24 24 is your answer
factor completely 6t^3 - 8t^2 - 30t
f(x) = 4.1cos9t the derivitative of just cos(9t) is -9sin9t then just multiply -9 by 4.1 (-36.9) the derivative is -36.9sin(9t)
-9w + zt + wz - 9t = (z - 9)(t + w)
9t + 15t= 216 24t=216 t=216/24 t=9
They are the same.
9t + 5 = 7 - 2t Subtract five from both sides: 9t = 2 - 2t Add 2t to both sides: 11t = 2 Divide both sides by 2 t = 2/11 or about .1818
