Simplifying Expressions (Part 2)

The video tutorial explains how to simplify expressions by using distribution and combining like terms. It begins by introducing the concept of distribution in expressions and identifying the number to distribute. The process of distribution is demonstrated, followed by combining like terms to achieve a simplified expression. The tutorial concludes with the final simplified expression, emphasizing the steps of distribution and combination.

What is the first step in simplifying the expression 3X + 2 times the sum of 5X and 7?

• Combine like terms

• Multiply 3X by 2

• Distribute the 2

• Add 5X and 7

Which number is distributed in the expression 3X + 2 times the sum of 5X and 7?

• 2

• 7

• 3

• 5

What is the result of distributing 2 to 5X in the expression?

• 15X

• 10X

• 5X

• 7X

After distribution, what is the new expression before combining like terms?

• 3X + 5X + 14

• 3X + 10X + 7

• 3X + 10X + 14

• 3X + 5X + 7

What is the final simplified form of the expression 3X + 2 times the sum of 5X and 7?

• 15X + 14

• 13X + 7

• 13X + 14

• 10X + 14
