The distributive property of multiplication over sum states that given three numbers a, b, and c:
a * (b + c) = a * b + a * c
Notice that, in this problem, we have:
a = 2
b = 7
c = 6
Then, we can say that the expression was rewritten using the distributive property of multiplication over sum.
When we first solve the sum inside the parenthesis, we find:
2 * (7 + 6) = 2 * 13 which equals 26
When we use the distributive property, we find:
2 * 7 + 2 * 6 = 14 + 12 which equals 26
