My guess would be B.
Don't quote me on this lol.
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.

LUFFY to the right and LUFFY to the left
So puppies will be 5x and Kittens 4 x so they combined will be 5x+4x=27
9x=27
X=3
Answer:
Step-by-step explanation:
We are given the equation . To find y-value when or at x = 3, simply substitute x = 3 in which gives us then evaluate the value as we obtain the y-value or final answer to the question:
