Answer:

Step-by-step explanation:

The degree of the polynomial is the highest exponent of an expression. When more than one variable is present, its is the sum of exponents on one term in the expression.

The polynomial has terms xy, 3x^2, -7 and x. The term with the highest exponent sum is xy or 3x^2. Both have degree 2. The degree of the polynomial is 2.

What is the area of the two rectangles shown below?

DedPeter [7]

Answers are in bold.

For the first one:

The total area of both shaded and unshaded portions is equal to $3x(4x+7)$ , which simplifies to $12x^2}+21x$ . The area of the middle white portion is $(5x)(2x)$ , which simplifies to $10x^2$ . To find the area of the shaded portion, we do $12x^2}+21x - 10x^2$ . Combining like terms, we get $2x^2+21x$ as our expression for the area of the shaded portion of the first rectangle.

For the second one:

The total area of both shaded and unshaded portions is equal to $6n(8n+14)$ , which simplifies to $48n^2}+84n$ . The area of the middle white portion is $10n(4n+1)$ , which simplifies to $40n^2+10n$ . To find the area of the shaded portion, we do $48n^2+84n-40n^2+10n$ . Combining like terms, we get $4n^2+94n$ as our expression for the area of the shaded portion of the second rectangle.
