Question

The distributive property of multiplication justifies which of the following statements?

A 4(y – z) = 4(y) + 4(-z)
B 3(s) + 3(t) = 9(st)
C 8 + (-8) = 0
D (a + b) + c = (c + a) + b

Answer 1

The answer is: [A]:
_________________________________________________
" 4(y – z) = 4(y) + 4(-z) "
_________________________________________________

Note the "distributive property of multiplication" :
_________________________________________________
a(b+c) = ab + ac ; AND:
a(b−c) = ab − ac ;
__________________________________________________

Answer 2

A since you distribute the 4
