In the expression 4(2m-n), determine which of the following best describes the role of 2
2 answers:
Answer: option D. 2 is a coefficient.
Explanation:
1) The expression 4 (2m - n) is a polynomial in its factored form.
2) There are two factors: 4 and 2m - n
3) The second factor, 2m - n, is a binomial. It means that it is formed by two monomials or terms: 2m and n.
4) The number in front of a term, in this case 2m, is named coefficient. Therefore, the number 2 is the coefficient of the term 2m.
In general, a term is a monomial, which is a expression of the kind:
Where:
- α is the coefficient
- x, y, ans z are the variables
- a, b, and c are the exponents of each variable
- a+b+c is the degree of the term

In a right angle, the sum of the squares of the two shorter sides is equal to the square of the longest side.
Here, the longest side is 25, the shorter sides are x and x+5.
The length of a side must be a positive number, so x=15.
The answer is C.
