Question

A rectangle has sides measuring (6x + 4) units and (2x + 11) units. Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points) 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)

Answer 1

Answer:

area of triangle = (6x + 4)*(2x + 11) , degree is 2 and closure property is

(6x + 4)*(2x + 11) =   (2x + 11)*(6x + 4)

Step-by-step explanation:

as the area of triangle is length * breadth, and here length is (6x +4) and breadth is (2x +11)

hence, area = (6x + 4)*(2x + 11)

and as area = (6x + 4)*(2x + 11), by multiplying binomial by binomial, we get

12x² + 8x + 66x + 44 so, here the degree means highest power of a variable and here it is 2.

so, degree of the expression is 2

closure property is a*b = b*a

so, (6x + 4)*(2x + 11) =   (2x + 11)*(6x + 4)

so the Question is answered
