Answer:
- A. 7·6 + 7·3
- B. 7·3 + 7·6
- C. 7·9
Step-by-step explanation:
The distributive property and the commutative property of addition both apply here.
Distributive property: a(b+c) = ab +ac
For a=7, b=6, c=3, this becomes ...
7(6+3) = 7·6 +7·3 . . . . . matches A
The commutative property of addition says ...
a + b = b + a
For a=7·6 and b=7·3, this becomes ...
7·6 + 7·3 = 7·3 + 7·6 . . . . . matches B
Of course, the expression can be partially evaluated:
7(6 +3) = 7·9 . . . . . matches C
