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

Identify the property illustrated in each statement. Assume all variables represent real numbers. (5x) • (1/5x) = 5 ( x • 1/x )

Identify the property illustrated in each statement. Assume all variables represent real numbers. 5 + √3 is a real number.

Rewrite each expression using the distributive property and simplify, if possible. See Example 7. 2(m + p)

Rewrite each expression using the distributive property and simplify, if possible. See Example 7. -12(x - y)
