Answer:
ok ill private message it to you wink
Step-by-step explanation:
Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.

Answer: 455 possible outcomes
Step-by-step explanation:
If there are 3 positions and 15 candidates, you multiply 15 by 14, then by 13 to get the number of possible outcomes times 6.
This is because once a candidate gets a position, there will be 1 less candidate without a position each time.
15 * 14 * 13 = 2,730
Now, since there are only 3 positions, the first position has 3 possible ways, the second position has 2 possible ways, and the third position has 1 possible way.
3 * 2 * 1 = 6
2,730 / 6 = 455
Do you need the steps? g=14
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
