Answer

distributive property, Commutative Property of Addition, Associative Property of Addition, combining like terms, Commutative property of Addition

Work Step by Step

5(x + 4) + 3x = (5x + 20) + 3x (distributive property) =(20 + 5x) +3x (Commutative Property of Addition) = 20 + (5x +3x) (Associative Property of Addition ) = 20 +(5+3)x (combining like terms) = 20 + 8x =8x + 20 (Commutative property of Addition)
