The correct expressions are:
a. 4(-3 + 15) = 4(12) = 48
d. 4(8 + 6 - 2) = 4(12) = 48
Therefore, expressions a and d are equivalent to 48.
a. 4(-3 + 15) = 4(12) = 48
d. 4(8 + 6 - 2) = 4(12) = 48
Therefore, expressions a and d are equivalent to 48.

Let's simplify the expression √3 • √12:
√3 • √12 = √(3 * 12) = √36 = 6
Since the result of simplifying the expression is a rational number (6), the correct statement is:
C. It represents the product of two rational numbers and is equivalent to a rational number.
√3 • √12 = √(3 * 12) = √36 = 6
Since the result of simplifying the expression is a rational number (6), the correct statement is:
C. It represents the product of two rational numbers and is equivalent to a rational number.
