Konichiwa~! My name is Zalgo and I am here to help you out today. If f were to equal -3, first we need to put -3 into the equation. It would look like "f(-3)=x^2". The answer to that equation is 9.

I hope that this helps! :T

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ?x - 49

shutvik [7]

We are asked to find unknown or the missing number to complete the polynomial given in the problem which is x² + ?x -49. First, let us equate the number to be equal to zero such as it would become x² + ?x - 49 = 0. Next, we need to find the factors such that it would produce a difference of squares and these two factors are a = +7 and b = -7. Hence, the complete solution is shown below:
(x + 7) (x-7) = 0
perform distribution and multiplication of terms such as shown below:
x² + 7x - 7x - 49 = 0
Combine the same term such as we can either add or subtract +7x to -7x and the result will be equal to 0x.
x² + 0x - 49 = 0

Therefore, the missing number is 0. The answer is 0 which will result to x² +0x - 49.

Given the equation, C = P + (P)(T), what is the final cost of a cell phone priced at $20.00 with a tax rate of 5%?

sergij07 [2.7K]

Answer: Answer is $21

Step-by-step explanation:

Using the equation C = P + (P)(T)

where P= $20

T= 5%; 5/100 = 0.05

Substitute the figures in the equation,

$20 + $20 (0.05)

Apply BODMAS and open bracket first

$20 + $1

= $21

Find the smallest possible solution to 2/3x^2=24

Bezzdna [24]

$\dfrac{2}{3} x^2 = 24$

---------------------------------------------------------------------
Divide by 2/3 on both sides :
---------------------------------------------------------------------
$x^2 = 24 \div \dfrac{2}{3}$

---------------------------------------------------------------------
Change the divide fraction to multiplication fraction :
---------------------------------------------------------------------
$x^2 = 24 \times \dfrac{3}{2}$

---------------------------------------------------------------------
Simplify :
---------------------------------------------------------------------
$x^2 = 36$

---------------------------------------------------------------------
Square root both sides :
---------------------------------------------------------------------
$x = \pm \sqrt{36}$

---------------------------------------------------------------------
Answer :
---------------------------------------------------------------------
$x = \pm6$

---------------------------------------------------------------------
Answer: The smallest possible value of x is -6
---------------------------------------------------------------------
