1. 4 (6 + 7) is the same as (4 • 6) + (4 • 7)
    X = 4
2. 6 • 45 = 270
a. 270, (6 • 40) + (6 • 5) = 240 + 30 = 270
b. 210, (6 • 40) - (6 • 5) = 240 - 30 = 210
c. 270, (6 • 50) - (6 • 5) = 300 - 30 = 270
    A. 270, C. 270
3. 6m + 7n + 5m - 3n, combine like terms, 6m + 5m = 11m, 7n - 3n = 4n

4. 2y^3 - 4y^2 + y + y^3, exponents tell you what are like terms
    C. 2y^3 and y^3
