Answer:

                [tex]x_{1} =-14\\\\x_{2} =6[/tex]

Step-by-step explanation:

[tex]x^{2} +8x-84=0\\\\x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=1; \: \: b=8; \: \: c=-84\\\\x=\dfrac{-8 \pm \sqrt{8^{2}-4 \cdot 1 \cdot (-84) } }{2 \cdot 1}=\dfrac{-8 \pm \sqrt{400 } }{2}=\dfrac{-8 \pm20}{2} =-4 \pm 10\\\\x_{1} =-14\\\\x_{2} =6[/tex]

Answer:

x^14

Answer:

x^14

Step-by-step explanation:

Use the power rule a^m a^n=a^m+n  

x^5+9

add 5 and 9

Answer:

68°

Step-by-step explanation:

arctan(x) = 5/2

Answer:

Wouldnt the answer be "D"

Since it's negative number and multiplied

But still not sure.

[tex]area = lw[/tex]

[tex]area = (8)(8)[/tex]

[tex]area = 64 \: {inches}^{2} [/tex]

//

[tex]perimeter = 2(l) + 2(w)[/tex]

[tex]perimeter = 2(8) + 2(8)[/tex]

[tex]perimeter = 32 \: inches[/tex]

Answer:

He will read 1/2 more than Philippe

Step-by-step explanation:This will be because is Rafael reads 1/2 and Philippe reads 1/2 of that it would still be 1/2

Given diameter is 32, radius would be 16 bc radius is always half of diameter, and circumference would be 2(pi)*radius, which would be 100.5309649.... and area is (pi)*radius^2 which would be 804.2477193........

Answer:

x = -40 and y = -64

Step-by-step explanation:

The ratio of the two numbers is 5/8, since the difference of these two numbers is 24, what is the sum

Let two numbers be x and y.

ATQ,

x-y = 24 ..(1)

and

[tex]\dfrac{x}{y}=\dfrac{5}{8}[/tex]

or

8x-5y =0 ...(2)

Multiply equation (1) by 8.

8x-8y = 192 ...(3)

Subtract equation (3) from (2).

8x-5y -(8x-8y) = 0-192

-5y+8y = -192

3y = -192

y = -64

Put the value of y in equation (1).

x-(-64) = 24

x+64 = 24

x = -64+24

x = -40

So, the values of x and y are -40 and -64 respectively.

Step-by-step explanation:

Answer:

<2, <3, <4

Step-by-step explanation:

You have parallel lines cut by a transversal, so alternate interior angles are congruent. Also, alternate exterior angles are congruent. Corresponding angles are congruent.

Vertical angles are always congruent.

I'll write each congruent angle and the reason.

<2, vertical

<3, corresponding

<4, alternate exterior angle

Answer:

11

Step-by-step explanation:

Work backwards and reverse the operations to find the original number.

Reverse the operations for add four: 8 - 4 = 4

Reverse the operations for take the square root: 4² = 16

Reverse the operations for subtract six: 16 + 6 = 22

Reverse the operations for double the number: 22 ÷ 2 = 11

Answer:

22

Step-by-step explanation:

We substitute the numbers for the letters to get 4*4 + 3*2 and then we multiply. 16 + 6 which equals 22. I hope this helps and please mark brainliest!

Answer:

22

Step-by-step explanation:

4a + b2

4(4) + (3)2

4 x 4 = 16

3 x 2 = 6

16 + 6 =

Answer:

Mean = 3.5

Median = 3.5

Mode = 5, 2

Step-by-step explanation:

Hope that helps!

Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:

Mean: (5 + 2 + 5 + 2)/4

= (14)/4

= 3.5

Mean = 3.5

Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):

Median: (2 + 5)/2

= 7/2

= 3.5

Median: 3.5

Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.

Mode: None.

Range: The Range is found by subtracting the greatest number with the least number:

5 - 2 = 3

Range: 3
