Respuesta :
Using GCF and Distributive property on the sum of 42 and 66 gives us;
((6 * 7) + (6 * 11) = 6(7 + 11)
GCF simply means the greatest common factor. Now, to find the GCF of 42 and 66, let us state their factors;
Factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42
Factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66
The highest factor common to 42 and 66 is 6. Thus, we can say that the GCF of 42 and 66 is 6.
- We want to add 42 to 66.
42 + 66
The distributive property states that;
a(b + c) = ab + ac
Thus;
Since GCF of 42 and 66 is 6, then we have;
42 + 66 = ((6 * 7) + (6 * 11)
Using distributive property;
((6 * 7) + (6 * 11) = 6(7 + 11)
