Answer 9

ok thank you you are a big help

Answer 10

In 1., all that was changed was the order of the multiplication.
Think of n + 6 as A.
A * 7 = 7 * A
A change of order is the commutative property of multiplication.

Answer 11

In 2., the grouping changed. On the left, you need to do 4 * 9 first, then multiply by 3.
On the right side, 3 * 4 is done first, then it is multiplied by 9. The grouping has changed. Change of grouping is the associative property of multiplication.
