All literal equations have how many variables?

a) less than two
b) exactly two
c) more than two
d) more than one

C more than one because have you ever seen a formula that has one variable? For instance, x is not a literal equation. A=bh is a basic literal equation there is no cap on a number of variables that can be in a literal equation as long as it is more than one.

Ibelieve 4mn because it’s like you’re combining them
