A rectangle has sides measuring (4x + 5) units and (3x + 10) 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)

Part A:

Area of a rectangle: A = lw

A = (4x + 5) * (3x + 10)

A = 12x² + 55x + 50

Part B:

The degree of the expression is 2 and it is a trinomial. A quadratic binomial.

Part C:

Part A demonstrates the closure property of polynomials because the product of the 2 polynomials is a polynomial.

A. 12x² + 55x + 50

B. Degree: 2

C. Product of two polynomials is also a polynomial

Step-by-step explanation:

(4x + 5) × (3x + 10)

12x² + 15x + 40x + 50

12x² + 55x + 50

This is a quadratic (degree 2) polynomial
