we have the expression
-20 + 5p - 7z
there are three terms -----> is a trinomial (The terms are the numbers or the variables added together)
terms -----> -20 5p and -7z
the coefficients (the coefficient is the number multiplied to the variable) of the variables are
5p ------> coefficient is 5
-7z ----> coefficient is -7
-20 ---> is a constant
the answer is
terms are -20, 5p, -7z
coefficients are 5 and -7
