[tex] \sqrt{ {x}^{2} - 4 } \times \sqrt{x {}^{2} - 9} [/tex]
​

Answer:

-8

Step-by-step explanation:

6(x-1) = 9(x+2)

6x - 6 = 9x +18

-24 = 3x

-24/3 = x

x = -8

Hope this helps!!

Answer:

6(x-1)=9(x+2)

6x-6=9x+18

-18-6=9x-6x

-24=3x

-24/3=3x/3

-8=x

Step-by-step explanation:

Use formula of midpoint

( x1+x2)/2 , (y1+y2)/2

2+8 = 10/2 = 5 (x)

3+ -4 = -1/2 (y)

(5,-1/2) is the final answer

Answer: 30x + 150

Step-by-step explanation:

Answer:

(x+2)^2-6

Step-by-step explanation:

(x+2)^2 = x^2 + 4x + 4

x^2 + 4x + 4 -6 = x²+4x-2

Answer:

(x + 2)² - 6

Step-by-step explanation:

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² + 4x

x² + 2(2)x + 4 - 4 - 2

= (x + 2)² - 6

Answer:

You are correct! But note the syntax:

the computer wants you to type in the box

2/3 x - 2

because "y =" is already written!

Step-by-step explanation:

Answer:

The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes. This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes ).

Step-by-step explanation:

Answer:

Below

Step-by-step explanation:

First let us create an equation for this problem

     (24 cupcakes)( $ of each cupcake) + ( $16 layer cake ) = $52

Let's say that C will represent the $ of each cupcake to make it easier

Solving it....

     24C + 16 = 52

     24C = 36

Divide both sides by 24

          C = 1.5

Therefore, each cupcake cost $1.5

We can check to see if this works....

     24(1.5) + 16 = total cost

            36 + 16 = 52, so this is correct

Hope that helped! Best of luck <3

Answer:

73%

Step-by-step explanation:

/ means divide

you divide the total by those who showed up

27/37 = .7297 = around .73 = 73%

Answer:

-4 - 8i

Step-by-step explanation:

The complex conjugate of -4 + 8i=-4 - 8i

Answer:

so.. it cannot be same

Step-by-step explanation:

. the perimeters may be same but the area cannot.  

We've been looking at two rectangles with the same area, and talking about the perimeter of those shapes. We found out that rectangles that have the same area don't necessarily have the same perimeter. owo

Answer:

Correct choice is option A. 6a + 8b ≤ 200

                                             7a + 5b ≤ 150

---> cereal A with grams will be multiplied by the sodium available in one gram of cereal A

----> The solution from the above equation would then be added to the cereal B with grams as well as its sodium content per grams.

6a + 8b ≤ 200

---> Cereal A's grams × Cereal A's calories + Cereal B's grams × Cereal B's calories is ≤ 150

so, 7a + 5b ≤ 150

Answer:

g(x) = |x-10|

Step-by-step explanation:

In majority of cases, the h in an equation is the movement to the left and right. and if you subtract h, you move to the right, if you add h, you move to the left. So in this case, to move ten units to the right, you would have h=10. Because there are no other changes made to the equation, the new equation, g(x), is simply:

g(x) = |x-10|

Answer:

1440

Step-by-step explanation:

Let's say x = number of hours worked per week for 12 people. Now one worker works 30 hours a week so if you multiply 12 workers by 30 you will get how many hours 12 workers worked. so x = 12 • 30. 12 • 30 is 360. so x = 360 or for 1 week 12 workers worked 360 hours. now we need to find the amount of hours for 4 weeks. so we can do 4x or 4 times the amount of hours per one week. since x = 360. 4 • 360 = 1440.

Step-by-step explanation:

Answer:

2x + 2

Step-by-step explanation:

Given

[tex]\frac{x^3+2x^2}{x}[/tex] ( divide each term on the numerator by x )

= x² + 2x

Differentiate each term using the power rule

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] , then

[tex]\frac{d}{dx}[/tex] (x² + 2x ) = 2x + 2

Hi! I'm happy to help!

To solve for WX, we have to find the length of the part of the line that isn't XY. Since we know the full length of the line, we subtract the length of XY from WY to get WX:

100-89.6

10.4

The length of WX is 10.4 centimeters.

I hope this was helpful, keep learning :D

Answer: WX = 10.4 cm

Concept:

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

XY = 89.6 cm

WY = 100 cm

Given expression deducted from the segment addition postulate

WX = WY - XY

Substitute values into the expression

WX = 100 - 89.6

Simplify by subtraction

WX = [tex]\boxed{10.4cm}[/tex]

Hope this helps!! :)

Answer:

profit of $140,910

there is a missing number I will assume that the probability is 1 in 11,000

company expected revenue per policy = $600

companies expected expense = 400,000 * (1/11,000) = -36.36

profit per policy = $536.64

$536.64*250 = $140,910

Step-by-step explanation:

Answer:

Both are true

Step-by-step explanation:

y = 6x and (8, 48)

48 = 6(8)

48 = 48

TRUE

5 - x = y and (2, 3)

5 - 2 = 3

3 = 3

TRUE
