Unit 6 Review

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width)

Front

Calculate the perimeter of a rectangle with width (2x + 3) and length (2x - 4).

Back

Perimeter = 2 * ((2x + 3) + (2x - 4)) = 8x - 2

Front

What is the formula for the area of a rectangle?

Back

Area = length * width

Front

Calculate the area of a rectangle with width (3x + 1) and length (4x - 6).

Back

Area = (3x + 1)(4x - 6) = 12x^2 - 14x - 6

Front

What is the result of the operation (4x^2 + x) - (x^2 + 2x)?

Back

3x^2 - x

Front

Perform the operation: 2x + 3x.

Back

5x

Front

What is the product of (2x^2)(3x)?

Back

6x^3

Front

What is the definition of a polynomial?

Back

A polynomial is a mathematical expression consisting of variables, coefficients, and non-negative integer exponents.

Front

What is the degree of the polynomial 4x^3 + 2x^2 - x + 5?

Back

The degree is 3, which is the highest exponent.

Front

What is a like term in algebra?

Back

Like terms are terms that have the same variable raised to the same power.
