Question 1: Explain how the letter x (or any letter) is used when writing expressions, and give an example. How are expressions different than equations?
Question 2: Identify the parts (include: terms, coefficients, variables and constants) of the following expression and translate it into a verbal expression:
2(3x – 2y) + 7
Question 3: Identify the like terms, explain how you know they are like terms, and simplify the expressions:
10y + 3x + 10 +x -2y
3x – y + 4x + 6 – 2y
Question 4: Explain how to evaluate the expression 8x2 + 25y, when x = 3 and y = 2
Question 5: Explain how to write an equivalent expression for the expression
3(4x + 2y) + 5x.
Be sure to explain which properties you used. What method can you use to prove the 2 expressions are equivalent?
