Part A: The two factors of this expression are 9 and 7+2x. The first factor is a constant consisting of only one element. The second factor is a binomial which means it is consisted of two elements or terms.
Part B: As already described above, the first factor only has 1 term and the second, being a binomial, has two terms.
Part C: The term which is linked to the variable is 2x. This means that the numerical coefficient of the variable term is 2.
Moreover if we try to simplify the factors by distribution, we get, 63 + 18x This will then tell us that the coefficient of the variable term is 18.
The answer is 79 because 9/10 divided by 71.1 is 79. And if you want to check, you can multiply 9/10 by 79, which will give you 71.1. I hope this helped :)
