Answer:

\boxed{\sf Associative \:property\: of \:addition}

  • \sf (4 + 5) + 2 = 4 + (5 + 2)

\boxed{\sf Distributive \:property}

  • \sf 2(2x + 4) = 4x + 8

\boxed{\sf Associative\: property \:of \: multiplication}

  • \sf ( 7 * x ) *3 = 7 (x *3)

\boxed{\sf Commutative \:property\: of \:multiplication}

  • \sf ( 8* x *2) = (x *8* 2)

\boxed{\sf Commutative \:property \:of \: addition}

  • \sf ( 7 + 3) + 1 = 1 + (7 + 3)

________________________________

Associative property of addition: Changing grouping of addends doesn't change the sum.

Distributive property: Multiplying a sum by a number is the same as multiplying each addend by that number and then adding the two products.

Associative property of multiplication: Changing grouping of the factors doesn't change the products.

Commutative property of multiplication: Changing order of the factors doesn't change the products.

Commutative property of addition:  Changing order of addends doesn't change the sum.
