Answer:
<u>Similarity ratio is the ratio of corresponding sides:</u>
Correct choice is A
By the binomial theorem, the
term in the expansion of
is

which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,

Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:

It is provided that, Renee recognizes that 7 and
are reciprocals, so she would like to find their product before she multiplies by
.
The associative property of multiplication states that:

The commutative property of multiplication states that:

The distributive property of multiplication states that:

The identity property of multiplication states that:

So, Renee should use the commutative property of multiplication to find the product of 7 and
,

Thus, the correct option is commutative property.
