What is the value of b^2 when the expression is 1/2 (h) (b^1+b^2)

Answer:

x = 8

x = 21/14

x = 8

x = 15/21

x = 1/4

x = 7

Step-by-step explanation:

(For all instances of number, let it be x)

Double the sum of a number and 15. The result is the same as the product of 23 and the number.

2x + 15 = 23 + x

2x - x + 15 = 23 + x - x

x + 15 = 23

x + 15 - 15 = 23 - 15

x = 8

Multiply a number by 15 and add 2. The result is the same as the sum of 23 and the number.

15x + 2 = 23 + x

14x + 2 = 23

14x = 21

x = 21/14

Double a number and add 15. The result is the same as the sum of 23 and the number.

2x + 15 = 23 + x

x + 15 = 23

x = 8

Double a number and add 15. The result is the same as the product of 23 and the number. (This time we will move the x to the other side as the right side has a larger x than the left side)

2x + 15 = 23x

15 = 21x

x = 15/21

Multiply a number by 15 and add 2. The result is the same as the product of 23 and the number.

15x + 2 = 23x

2 = 8x

2/8 = x

x = 1/4

Double the sum of a number and 15. The result is the same as the sum of 23 and the number.

2(x + 15) = 23 + x

2x + 30 = 23 + x

x + 30 = 23

x = 7

Hope it helps

The three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

An irrational number is a number that cannot be expressed as a fraction {p/q} for any integers {p} and {q}.

Given are irrational numbers between 15 and 17​.

Now, we can write -

A = 15² = 15 x 15 = 225

{A} = 225

B = 17² = 17 x 17 = 289

{B} = 289

The irrational numbers between 15 and 17 can be written as the square root of numbers between 225 and 289. So, we can write -

[tex]$\sqrt{231.44}\\[/tex]

[tex]$\sqrt{244.57}\\[/tex]

[tex]$\sqrt{277.67}\\[/tex]

Therefore, the three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

Answer:

x=-2

Step by step explanation:

Step by step explanation:Subtract 2 from both sides:

6x + 2 - 2 = - 10 - 2

Simplify

6x = - 10 - 2

Simplify the arithmetic:

6x = - 12

Then Isolate x:

6x = - 12

Divide both sides by 6:

(6x)/6 = - 12/6

Simplify the fraction:

x = - 12/6

Find the greatest common factor of the numerator and denominator:

x = (- 2 × 6)/(1 ×6)

Factor out and cancel the greatest common factor:

x = - 2

Therefore,x=-2

Answer:

110°

Step-by-step explanation:

Since all angles on a straight line add upto 180°,

Angle 1 + Angle 2 = 180

Angle 1 + 70 = 180

Angle 1 = 180 -70

Angle 1 = 110°

Answer:

(18,23)

Step-by-step explanation:

Add distances:

7+4+7 = 18

9+5+9 = 23

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

A division is a process of splitting a specific amount into equal parts. 

We have,

(3x³ + 4x² - 2 + 7) ÷ (x + 2)

We will divide using the long division method.

Divident = Divisior x Quotient + Remainder

Divident = (3x³ + 4x² - 2 + 7)

Divisor = x + 2

We will find the quotient and the remainder.

  x + 2 ) 3x³ + 4x² - 2 + 7 ( 3x² - 2x

             3x³ + 6x²                   [ sign is changed, 3x³ = -3x³ and 6x² = -6x²]

                    - 2x² - 5

                   - 2x² - 4x             [ sign is changed, -2x² = 2x² and -4x = 4x ]

                            4x - 5

Quotient = 3x² - 2x

Remainder = 4x - 5

Thus,

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

Option C

The value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively utilized in various geosciences, including navigation, and solid mechanics.

Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.

The cosine ratio will be calculated by first calculating the perpendicular WZ.

WZ = 12 x tan60

WZ = 12 x √3

WZ = 12√3

Then calculate the hypotenuse of the triangle.

XZ² = 20.78² + 12²

XZ² = 430+ 144

XZ² = 574

XZ = 24

The cosine ratio will be calculated as:-

cosФ = Base / hypotenuse = 12 / 24.

Therefore, the value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.
