Front

What is the formula for the area of a rectangle?

Back

Area = Length × Width

Front

If the area of a rectangle is 18 sq. ft. and the width is 3 ft., what is the length?

Back

Length = Area ÷ Width = 18 ÷ 3 = 6 ft.

Front

What is the order of operations in mathematics?

Back

PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Evaluate the expression (3 + 4)·3 + 30÷3.

Back

= 7·3 + 10 = 21 + 10 = 31.

Front

What is the x-intercept of a linear equation?

Back

The x-intercept is the point where the graph crosses the x-axis (y=0).

Front

How do you find the x-intercept of the equation 2x + 5y = 20?

Back

Set y = 0: 2x + 5(0) = 20, so x = 10.

Front

What is a quadratic function?

Back

A function that can be expressed in the form f(x) = ax^2 + bx + c, where a ≠ 0.

Front

How do you graph a quadratic function?

Back

Create a table of values for x, calculate corresponding y values, and plot the points.

Front

What does the graph of y = x^2 - 4x + 6 look like?

Back

It is a parabola that opens upwards with a vertex at (2, 2).

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using <, >, ≤, or ≥.
