Remind students that in exponential notation, the base is a repeated factor, and does not indicate repeated addition. I have an idea. If you substitute a number in for x, like 2, you get 6 for both expressions. Let me give you an example of the distributive property using numbers.

Students struggle to understand that x5 and 5x are equivalent expressions, because it conflicts with their previous experiences with numbers 53 and 35 are not equivalent.

But back to our original task of generating equivalent expressions for the area of the rectangle. I already drew a picture to show what that might look like. You could add all the x s together and add all the 1 s together.

Is there another way to write that expression that may be a little simpler? What would that be? Questions Eliciting Thinking What does it mean for expressions to be equivalent? Like we usually write 3x, not x3. It is true that in algebra, when we write quantities right next to each other without any symbol in between, multiplication is implied.

Because of the commutative property. Give me an example. I know an easier way to do the problem. I know that properties are somewhat like laws; they always work. Demonstrate that two expressions [e.

Be sure the student understands that the Distributive Property applies to subtractions as well since any subtraction can be rewritten as an addition. So how can we use the associative property to find more equivalent expressions for the area of our rectangle?

I see what you mean. In the first expression you multiply 3 times 2, and in the second expression you multiply 2 times three. Writing the 3 at the end of the expression instead of the beginning.

What part is confusing you?Aug 10, · Learn how to take an expression like 12a+8b and rewrite it using the distributive property. Aug 10, · Rewrite an 2(9 +5k) and 5(3m+2) using the distributive property. Skip navigation Use Distributive Property to Write an Equivalent expression # 7, # 8 Simplifying Variable Expressions.

Algebraic expressions (6th grade) Write equivalent expressions using the Distributive Property of Multiplication over Addition An updated version of this instructional video is available.

May 21, · To use the distributive property to solve an equation, multiply the term outside the parenthesis by each term inside the parenthesis. For example, if there is a 4 outside the parenthesis and an x minus 3 inside of them, change it to 4 times x minus 4 times %(17).

Use the distributive property to write an equivalent expression Y (u+7) 5t+6t+to 24+12s+12 7 (u+4+h) Math Write an expression that is equivalent to 36+24, using gcf and distributive property.

Terms like 3x and 7x that have the same variable part are called like terms. The constant terms are like terms as well. Like terms can be combined as is stated in the distributive property. $$3x+7x=\left (3+7 \right)x=10x$$ Expressions like 3x+7x and 10x are equivalent expressions since they denote the .
