Evaluate each expression. See Example 5. -8 + (-4) (-6) ÷ 12 4 - (-3)

Evaluate each expression for p = -4, q = 8, and r = -10. See Example 6. 3p - 2r

Evaluate each expression for p = -4, q = 8, and r = -10. See Example 6. -p² - 7q + r

Evaluate each expression for p = -4, q = 8, and r = -10. See Example 6. (q + r)/ (q + p)

Evaluate each expression for p = -4, q = 8, and r = -10. See Example 6. (-(p + 2)² - 3r)/(2 - q)

Identify the property illustrated in each statement. Assume all variables represent real numbers. 6 • 12 + 6 • 15 = 6(12 + 15)

Identify the property illustrated in each statement. Assume all variables represent real numbers. (t - 6) • ( 1/(t-6)) = 1, if t - 6 ≠ 0

Identify the property illustrated in each statement. Assume all variables represent real numbers. (7.5 - y) + 0 = 7.5 - y
