Calculate the chage in enthalpy produced by dissolving 14.3 g NaOH in 65.0 g of water if the temperature increases 49.1 C and the specific heat of water is 4.18 J/g C.
So this is just q=mcΔt
Do you add 14.3 and 65.0 to use for m? Also would the sign for enthalpy be negative because heat is lost by the reaction and gained by the surroundings, which increased in temperature?

No, don't add the masses.
enthlapy is negative when heat is given off. In this case, it is +
