The questions below will help you keep track of key concepts from this lesson's study activity. Use the study page numbers listed to help you fill in the blanks or solve the problems. algebraic expressions: base: coefficient: constant: distributive property: exponent: exponential expression: like terms: standard order of operations: term: variables: Page 4 A(n) represents an unknown or changeable value. Page 5 Fill in the blanks to interpret the parts of the expression 9x + 4y – 5. Rewrite the expression as a sum: The expression has terms. List the terms: List the coefficient(s) used in the expression: List the constant(s) used in the expression: Pages 6 and 7 Use the properties of operations and combine like terms to completely simplify each expression. Simplify 2(x – 4) + 32: Simplify 9x + 4(x + 2) – 5: Page 8 Evaluate this expression for x = 4: 4 • (x – 2)2 – 9 Evaluate this expression for x = 5: 6 + (10 – x)2 – 20 Pages 15 – 17 Rami buys 3 pounds of oranges.
