The base of a triangle measures (2x+7) units and the height measures (4x+6) units.

part a- what is the expression that represents the area of the triangle? show your work to receive full credit hint: area=0.5bh

part b- what are the degree and classification of the expression obtained in part a?

part c- how does part a demonstrate the closure property for polynomials?

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.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
