No its 20 u should know that
In functions, the coefficient is the number that multiplies the variables, for example, for 5y, the coefficient is the number "5"
The "leading coefficient" refers to the number that multiplies the greater term of the expression (i.e. the term with the largest exponent), and if the terms are ordered from greatest to least, it corresponds to the coefficient of the first term.
So for the expression

The first and the term with the largest exponent is:

Where "6" is the coefficient of the term and thus the "leading coefficient" of the expression.
Answer:
Answer is D.
Lymphocytes.
Explanation.
How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.
