Explain how to use the distributive property to find the product (3) ( 4 1 5 ) .

The value of the expression (3) ( 4 + 1 + 5 )  using the distributive law is 30

Given the integers A, B, and C, according to distributive law:

A(B+C) = AB + BC

Applying the concept on the expression (3) ( 4 + 1 +5 ) 

(3) ( 4 1 5 ) = 3(4) + 3(1) + 3(5)

Note that 3 is distributed over the values 4, 1 and 5. On expansion

(3) ( 4 1 5 )  = 12 + 3  + 15

(3) ( 4 1 5 )  = 30

Hence the value of the expression (3) ( 4 + 1 + 5 )  using the distributive law is 30
