Consider the expression 4n3+ 3n2 + 2n + 1. What is the coefficient of n2?

3

Step-by-step explanation:

4n^3+ 3n^2 + 2n + 1.

The coefficient is the number in front of the term

3n^2  the coeffiecient is 3

answer: 5

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
