Let b=the number of boxes, c=cost of the pens
The expression that represents the total cost of the pens if a box costs 4 dollars and then she gets a 1 dollar discount for every additional box is c(b)=3b+1. We got this from the original equation c(b)=4+(4-1)(b-1). Simplify this and you will get c(b)=3b+1.
We need another number, we can't find the greatest common factor of one number :)
We know that statement 1 is always true.
But if we have a scalene trapezoid, it has neither equal angles nor equal sides, so 2 and 3 would not be true
