Solving a proportion with a binomial

The video tutorial explains how to use the cross product in mathematical equations. It starts with a simple example and progresses to a more complex scenario involving the distributive property. The instructor demonstrates solving the equation and simplifying the result, emphasizing the importance of understanding each step for an upcoming quiz.

What is the result of the cross product in the simple example given in the video?

• 4 * 12 = 3 * X

• X * 3 = 12 * 4

• 4 * X = 3 * 12

• 3 * X = 4 * 12

In the complex example, what operation is used to handle the expression 12 * (X + 1)?

• Distributive Property

• Addition

• Multiplication

• Subtraction

Which property allows us to multiply 12 by both X and 1 in the expression 12 * (X + 1)?

• Commutative Property

• Associative Property

• Distributive Property

• Identity Property

What is the first step in solving the equation 20 = 12X + 12?

• Multiply both sides by 12

• Divide both sides by 12

• Subtract 12 from both sides

• Add 12 to both sides

After simplifying the equation, what is the value of X?

• 3/4

• 1/3

• 2/3

• 1/2
