Question

which property is used in the following ? $7 \times (8 + 3) = 7 \times$
none of these
commutative property
associative property
distributive property

Explanation:

The given expression follows the rule that a number multiplied by a sum can be rewritten as the sum of the number multiplied by each addend, which defines the Distributive Property. The full form would be $7 \times (8 + 3) = 7 \times 8 + 7 \times 3$. The Commutative Property involves reordering terms, and the Associative Property involves regrouping terms, which do not apply here.

Answer:

Distributive Property
