Friday Algebraic Expressions

Objectives I will model algebraic expressions.
I will replace a variable with a given value and then evaluate the answer. I will use the distributive property to rewrite an expression and simplify.

Write a variable expression for each model. Squares represent ones(1)
Write a variable expression for each model. Squares represent ones(1). Rectangles represent a variable (x). 2. 1. 3.

SPI Model algebraic expressions using algebra tiles.

SPI 0606.1.5 Model algebraic expressions using algebra tiles.

Write an algebraic expression to represent this model.

Evaluate each algebraic expression
3m; where m = 9 4y + 6; where y = 6 2 (4e); where e = 5 3pq; where p=3 and q = 5 7n – (m + 18); where n = 4 and m = 10

Simplify each expression by combining like terms and complete all operations.
2m m 5(2m • 2) + 8m

SPI 0606.3.4 Rewrite expressions to represent quantities in different ways.

Simplify this expression and write the operations that were performed in each step.
4 (m + 8) + 5m

Simplify this expression and write the operations that were performed in each step.
4² (6n – 3n) + 85
