Your answer is correct.
-
Use the chain rule for derivatives
d/dx (5x+4)^0.5 = 0.5 (5x+4)^-0.5 d/dx (5x+4) = 2.5 / sqrt(5x+4)
d/dx (5x+4)^0.5 = 0.5 (5x+4)^-0.5 d/dx (5x+4) = 2.5 / sqrt(5x+4)

The function is a power function, so apply the Power Rule
All of this is in your book, but you must read it to find it.
Good Luck, you apparently will need it.
