Answer is -(8a + 1)

Step-by-step explanation:

  • Step 1: Given f(a) = 3a - 1 and g(a) = a + 4a. Now find f(4a) and g(4a)

⇒ f(4a) = 3(4a) - 1 = 12a - 1

⇒ g(4a) = (4a) + 4(4a) = 4a + 16a = 20a

  • Step 2: FInd the difference between f(4a) - g(4a)

⇒ f(4a) - g(4a) = 12a - 1 - 20a = -8a - 1 = -(8a + 1)
