Answer:
(6x + 9y)(6x - 9y)
Step-by-step explanation:
We can use the difference of squares which states that a² - b² = (a + b)(a - b), in this case, a = 6x and b = 9y so the answer is (6x + 9y)(6x - 9y).
Answer:
I think it's -3,9 there are 7 boxes between a and b and there are 7 boxes between point a and 9
That is called the multiplicative identity property.
<u>Given</u>:
The given expression is 
We need to determine the simplified value of the given expression.
<u>Simplification</u>:
Since, the given expression is in the form of
, the given expression can be simplified using the identity 
Comparing the given expression with the identity, we get;
and 
Using this in the identity, we get;

Simplifying, we get;

Thus, the simplified value of the given expression is 
Hence, Option c is the correct answer.
X - y
4 - 5 = -1
The difference between x and y is -1.
8 - 1 = 7
The answer for when y = 8, x = 7.
