I = Adt; where p = $290 is the Amount of the loan, d = 16% = 0.16 is the discount rate and t = 90days = 90/365 = 18/73 is the period.
I = 290 x 0.16 x 18/73 = 11.44
Interest = $11.44
Proceed = Amount - Interest = 290 - 11.44 = $278.56
<span>In abstract algebra and formal logic, the distributive property of binary operations generalizes the distributive law from elementary algebra. In propositional logic, distribution refers to two valid rules of replacement. The rules allow one to reformulate conjunctions and disjunctions within logical proofs.</span>
The only thing you could factor out is X so it would be
X(4x-5)
Subtract 
from both sides to get
