find the value of x. Round the length to the nearest tenth.

Answer:

Step-by-step explanation:

[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]

Take cube,

[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]

x + 4 = - (2x + 8)

x +4 = 2x *(-1) + 8 *(-1)

x+ 4 = -2x - 8

x +2x+4 = - 8

3x + 4 = - 8

      3x = - 8 -4

      3x = -12

        x = -12/3

x = -4

Answer:

No

Step-by-step explanation:

the pythagorean theorem is

a^2+b^2=c^2

These numbers do not fit in these terms

Answer:

It doesn't.

Step-by-step explanation:

In order for something to be a {ythagorean triple, it must comply with the Pythagorean theorem, which is a² + b² = c²

Always remember, when plugging in the values into that equation, the exponent of two means to square the number, and a and b have to be the two smallest values (in this case, 6 and 12)

6² = 36

12² = 144

36 + 144 = 180

Now, we have to find if ti equals c². 13² equals 169

Therefore, 180 ≠ 169, therefore it IS NOT a Pythagorean triple.

Answer:

This question is incomplete since you did not provide the options needed. Anyway, I will give you an explanation that will be useful for you to understand this.

Step-by-step explanation:

Understanding what a function is will allow you to have more clarity when solving the functions exercises and you will be prepared to understand more concepts that surround functions such as domain, image, relative extremes, their representation on the axes, etc.

A function is a relationship between two variables, one independent (x) and the other dependent (y) and for each value of x there corresponds ONE SINGLE VALUE OF y.

For example :

f(x) = 3x2 + 1

Answer: 36.9

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos or Tan.

To work out which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.

As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.

So first you would have to write:

Tanθ=3/4

Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.

θ=Tan-1 3/4

To find the answer you would have to put it in your calculator.

θ=36.9

Hope this helps :)

YES

Step-by-step explanation:

The 7 in (0,7) is the y-intercept given in the equation y = 3x + 7

Answer:c

Step-by-step explanation:

14, 21

Step-by-step explanation:

Let the two consecutive multiples be 7n and 7(n+1).

Now, it is given that:

(7n)² + [7(n+1)]² = 637

Simplifying,

49n² + (7n+7)² = 637

49n² + 49n² + 2(7n)(7) + 49 = 637

(as (x+y)² = x² + y² + 2xy)

98n² + 98n + 49 = 637

98n² + 98n - 588 = 0

Dividing by 98 to further simplify,

n² + n - 6 = 0

Factorising, we get

n² + 3n - 2n - 6 = 0

n(n+3) - 2(n+3) = 0

(n+3)(n-2) = 0

Therefore we get n = -3 or n = +2.

Hence, we get the consecutive multiples as 14 and 21.

Feel free to ask if you didn't understand any part.

Hope this helps! :D

Answer:

72.25

Step-by-step explanation:

12.5 x 8.5 = 106.25

5 x 6.75 = 33.75

106.25- 33.75 = 72.25

Answer: H

Step-by-step explanation:

You're tryna find the area of the wall

Which is the whole surface area minus the door's area

Whole surface area = 8.5 x 12.5 = 106.25

Door area = 5 x 6.75 = 33.75

106.25-33.75 = 72.5 ft^2

ALSO REMEMBER ITS FEET SQUARED

Units are very important just to let you know especially in physics

If you don't get the units to be same then its going to be one heck of a problem

okay no more ranting hope u like my answer

Answer:

Yes, all your answers are correct.

They are correctly matched with their reasons.

Answer:

think its two cuz i found a shape that matches ur questions

Answer:

the other two sides are 31.11 feet and 31.11 feet

Step-by-step explanation:

since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.

A right triangle is formed by a line from its peak down & perpendicular to

the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.

cos 50 = 20/x

0.6428 = 20/x

x = 31.11 feet

Answer:

the first one is -9/40. the second one is 109/20. the third one is -8/35.

Step-by-step explanation:

here is the work for the first one 3/8-.6 and convert into a simplified fraction and came up with -9/40. here is the work for the second one 4 4/3+0.7 and then convert into a simplified fraction and came up with 109/20. here is the work for the third one 4/7-0.8 and then convert into a simplified fraction and came up with -8/35.

Answer:

Step-by-step explanation:

|14-(6-x)| = |14-6+x| = |8+x|

|8+x| = 8+x if x > -8

|8+x| = -x-8 if x < -8

|8+x| = 0 if x= -8

Answer:

Correct answer

V(t) = 25000(0.86) t

Step-by-step explanation:

You wont turn 14% into a multiplier (1.14 - multiplier) becuase the value decreases not increases so you do 100% - 14% to get 86% and divide by 100 to get 0.86...that's the value that goes in the brackets

Step-by-step explanation:

Answer:

(x + 6) (x - 1)

Step-by-step explanation:

2x² + 10x - 12

dividing by 2,

x² + 5x - 6

x² - x + 6x - 6

x(x - 1) + 6(x - 1)

(x + 6) (x - 1)

x = -6 or x = 1

Answer:

62 degrees

Step-by-step explanation:

you need to understand the def.ang.biscectors, it is going to mean if a life bisects another line, the two angles on one side will add up to 180

therefore

180-118=62

Answer:

9

Step-by-step explanation:

Answer:

( 1 ), ( 3 ), ( 9 )

Step-by-step explanation:

Every time you add one to a digit (which is the same as adding 10, 100, 1000, etc) you get a number that is one more than a multiple of 9, so you have to subtract one from the number, which brings the sum of the digits back to 9.

Answer:

4/76 or simplified as 1/19

Step-by-step explanation:

5/20 is for the probability of the first balloon

4/19 is for the probability of the second balloon

5/20 can be simplified to 1/4 so 1/4 x 4/19 = 4/76

4/76 can also be simplified to 1/19
