What is the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d? a) -34
b) -1
c) 0
d) 1

When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?
