Answer: C

Step-by-step explanation:

The domain is all real values of x such that x is less than or equal to zero.

If x is greater than zero then all the positive numbers will make the number in the square root negative and that will become an imaginary number.

If x is zero then the number in the number will be 0 and find the square root of 0 is possible.

Cannon balls for an antique cannon are stacked next to it in four layers to form a square pyramid. How many cannon balls are in

labwork [276]

The amount of balls in a given layer can be found by squaring the layer it is in

4 layers
top layer (1st) is 1
2nd is 4
3rd layer is 9
4th is 16

add them up
1+4+9+16=30

30 in that pyramid

49x2 - 81 is an example of the difference of two

Shkiper50 [21]

Answer:

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.

Step-by-step explanation:

Formulas are used to factorize the polynomials.

In the given question, we can see a difference of squares

the difference of squares can be factorized using the formula

$a^2-b^2 = (a+b)(a-b)$

Here a^2 and b^2 are squares and factorized as sum and difference of numbers.

So in the given options,

(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
