What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

Front

How do you simplify the expression 3(10 - 8x)?

Back

You apply the distributive property: 3 * 10 - 3 * 8x = 30 - 24x.

Front

What is the difference between an equation and an expression?

Back

An equation has an equal sign (e.g., 2x + 3 = 7), while an expression does not (e.g., 2x + 3).

Front

How do you simplify the expression 2(-8 + 7c)?

Back

You apply the distributive property: 2 * -8 + 2 * 7c = -16 + 14c.

Front

What does it mean for two expressions to be equivalent?

Back

Two expressions are equivalent if they have the same value for all values of the variables.

Front

How do you combine like terms in the expression 4 + (-7) - 10x + 5x?

Back

Combine like terms: (4 - 7) + (-10x + 5x) = -3 - 5x.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable (e.g., in 5x, 5 is the coefficient).

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change (e.g., in 3x + 4, 4 is the constant).

Front

How do you identify like terms in an expression?

Back

Like terms are terms that have the same variable raised to the same power (e.g., 3x and 5x are like terms).

Front

What is the process for evaluating an expression?

Back

To evaluate an expression, substitute the values of the variables into the expression and simplify.
