The base of a triangle measures (3x − 6) units and the height measures (2x + 4) units. part a: what is the expression that represents the area of the triangle? show your work to receive full credit. (4 points) hint: area = 0.5bh part b: what are the degree and classification of the expression obtained in part a? (3 points) part c: how does part a demonstrate the closure property for polynomials? (3 points)

Part A: A = (0.5)(3x – 6)(2x + 4)

                 0.5(6x^2 - 24)

                  3x^2 - 12

Part B: Second degree binomial

Part C: Part A shows closure because when the polynomials are multiplied it equals a polynomial making it closure property.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
