which expression has a coefficient of positive 1 for the the term n ?
a. 5n^2+6n-1
b. 2n^2-5n+1
c. 3n^2+n-2
d. 4n^2-n+9

Step-by-step explanation:

Good evening ,

I guess it’s the C expression,

Because, C. 3n^2+n-2 so the coefficient of the term n is 1 and the coefficient of the term n^2 is 3

:)

The coefficient of a term is the number in front of the variable.

You are looking for positive 1 for the term n.

A has 6n, which means the coefficient is 6

B has -5n, so the coefficient is -5

C has just the term n, so this is actually 1n (positive 1)

D has -n, which would be -1n (negative 1)

The answer would be C.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
