Algebra-1

A. 2 + 7 = 7 + 2 This equation demonstrates the commutative property of addition, not multiplication.

B. 1 x 1 = 1 This shows the multiplicative identity property, where any number multiplied by 1 remains the same. It does not demonstrate the commutative property.

C. 2 x (3 + 4) = 6 + 8 This equation illustrates the distributive property, showing how to distribute multiplication over addition. It does not show commutativity.
