Which property is used in the problem? -2(x+7)=-2x-14 The Additive Identity Property The Commutative Property The Distributive Property The Associative Property

Answer 1

The property used in the problem \(-2(x+7)=-2x-14\) is the Distributive Property.

This property states that \(a(b+c) = ab + ac\). In this case, \(-2\) is distributed to both \(x\) and \(7\), leading to \(-2x - 14\).
