Question

2. Which of the following examples

demonstrates the distributive property:
a. x + 4 = 4 + x
b. 7(x - 4) = 7x - 28
C. 4 – 5 = 5 - 4
d. 9+ (4+5) = (9+ 4) + 5​

Answer 1

7(x-4)=7x-28

Explanation:

x+4=4+x is commutative

4-5=5-4 is also commutative

9+(4+5)=(9+4)+5 is associative

7 times x is 7x,

7 times -4 is -28
