-6(4x+9)

-24x-54 is the simplified answer of that expression.
-24x+54, not -54
A negative times a positive is negative.

Kid is right.
Distributive property:
-6(4x)=-24x
-6(9)=-54
The "-" is from the 6. Because -6(4x+9) is basically (-6)(4x)+(-6)(9) = (-24x)+(-54) = -24x-54. If you are adding a negative value, you are basically subtracting that value.
