Answer:
(c) commutative property of multiplication
Step-by-step explanation:
The associative properties of addition and multiplication let you move parentheses:
a + (b + c) = (a + b) + c . . . . . associative property of addition
a(bc) = (ab)c . . . . . . . . . . associative property of multiplication
__
The commutative properties of these operations let you change the order of the operands:
a + b = b + a . . . . . . commutative property of addition
ab = ba . . . . . . . . . commutative property of multiplication
__
If we look at this last statement with the idea that a=2 and b=(x+3) we can see that it matches the given expression:
2(x+3) = (x+3)2 . . . . commutative property of multiplication
