Answer: The right answer is A
Step-by-step explanation:
First of all, in the questions they ask for the product of [tex]2[/tex] and number, this number could be any number so [tex]"x"[/tex] could be a letter to replace this "any number"; so the product between [tex]2[/tex] and [tex]"x"[/tex] is equal to [tex]2x[/tex]
the last step is just minus eleven, so
[tex]2x[/tex] minus eleven is represented as = [tex]2x-11[/tex]
