A rectangle has sides measuring (4x + 5) units and (5x + 1) units.

Part A: What is the expression that represents the area of the rectangle? (6 points)

Part B: What are the degree and classification of the expression obtained in Part A?

Part A. A square is a two-dimensional shape with 2 sets of equal, parallel sides. The area of a square is equal to the square of its side. So, if the side measures (4x-7) units, then the area would be (4x-7)^2.

Part B. Let's expand the binomial in part A first. That would be equal to 16x^2 - 56x +49. There are different classifications of equation. There are linear equations, quadratic equations and exponential equations. In this case, the equation is a quadratic equation because it possesses the standard formula of a quadratic equation which is equal to ax^2 + bx + c = 0. On the other hand, the degree of the equation is the highest power of the variable. Since the highest degree is 16x^2, then the degree is 2.
