Front

What is the equation for the perimeter of a rectangle?

Back

The perimeter P of a rectangle is given by the formula P = 2(length + width).

Front

How do you solve for a variable in an equation?

Back

To solve for a variable, isolate the variable on one side of the equation using inverse operations.

Front

What does it mean for an equation to have multiple solutions?

Back

An equation has multiple solutions if there are infinitely many values that satisfy the equation.

Front

Back

The first step is to isolate the variable x by moving all terms involving x to one side and constant terms to the other.

Front

If the length of a rectangle is 1 inch longer than its width, how can you express the length in terms of the width?

Back

If the width is w, then the length can be expressed as l = w + 1.

Front

Back

The equation has multiple solutions because it simplifies to 0 = 0, which is always true.

Front

How do you find the dimensions of a rectangle given its perimeter?

Back

Use the perimeter formula P = 2(length + width) and solve for the dimensions based on the given perimeter.

Front

Back

The value of x is 3.

Front

What is the process of isolating a variable in an equation?

Back

Isolating a variable involves using algebraic operations to get the variable alone on one side of the equation.

Front

What does it mean to solve an equation?

Back

To solve an equation means to find the value(s) of the variable(s) that make the equation true.
