Respuesta :

Answer:

Distributive property in multiplication

a) 4.(20+8) = 4.20 + 4.8

Commutative law property in multiplication

b) (28) 4 = 4(28)

Step-by-step explanation:

Explanation:-

Distributive property in multiplication.

Let a ,b ,c are three numbers

a.(b + c) = a. b + a. c

Given problem 4(28) = 4(20+8)

4.(20+8) = 4.20 + 4.8

              = 80+32

             = 112

Commutative law property in addition

a + b =b + a

20 + 8 = 8 + 20

Commutative law property in multiplication

ab = b a

(28) 4 = 4(28)

Commutative law property in multiplication

let a, b and c are three numbers

a(bc) = (ab)c

4×(7×4) = (4×7)×4
