Final answer:
To use the Distributive Property, distribute 3 and 1 to each term inside the parentheses, then simplify and evaluate the expression.
Step-by-step explanation:
To use the Distributive Property to write the expression (3+1)(-6) as an equivalent expression, we distribute the 3 and 1 to each term inside the parentheses:
(3+1)(-6) = 3*(-6) + 1*(-6)
Simplifying, we get:
(3+1)(-6) = -18 + -6 = -24
So, the equivalent expression is -24.
