To Acquire=>the binomials below is a factor of

$x {}^{2} - 5x - 14$

Step-by-step explanation:

By Middle splitting method

=>

 $x {}^{2} - 5x - 14 \\ = x {}^{2} + 2x - 7x - 14 \\ = x(x + 2) - 7(x + 2) \\ = (x - 7)(x + 2)$ 

Hence, (x-7) Is the required answer

Hope it Helps

Answer:

Let's find it Out

To Acquire=>A Binomial out of the given options which is a factor of trinomial

Solution => 

 $x {}^{2} - 5x - 14 \\ = x {}^{2} + 7x - 2x - 14 \\ = x(x + 7) - 2(x + 7) \\ = (x - 2)(x + 7)$ 

<h2>Hence , (x-2) is the correct answer</h2>

Answer:

f^-1(x) = 4+∛((x-6)/5)

Step-by-step explanation:

To find the inverse function, solve ...

x = f(y)

then write the answer in functional form.

$\displaystyle x=f(y)\\\\x=5(y-4)^3+6\\\\x-6=5(y-4)^3\\\\\frac{x-6}{5}=(y-4)^3\\\\\sqrt[3]{\frac{x-6}{5}}=y-4\\\\y=4+\sqrt[3]{\frac{x-6}{5}}\\\\\boxed{f^{-1}(x)=4+\sqrt[3]{\frac{x-6}{5}}}$

The graph shows the function and its inverse to be reflections of each other in the line y=x, as they should be.

Find the area of a rhombus with side length 6 and an interior angle with measure $120^\circ$.

Serhud [2]

Answer:

The area of a rhombus is $18\sqrt{3}$ square units.

Step-by-step explanation:

Side length of rhombus = 6 units.

Interior angle of rhombus = 120°

another Interior angle of rhombus = 180°-120° = 60°.

Draw an altitude.

In a right angled triangle

$\sin \theta=\frac{opposite}{hypotenuse}$

$\sin (60)=\frac{h}{6}$

$\frac{\sqrt{3}}{2}=\frac{h}{6}$

Multiply both sides by 6.

$3\sqrt{3}=h$

The height of the rhombus is $3\sqrt{3}$ .

Area of a rhombus is

$Area=base\times height$

$Area=6\times 3\sqrt{3}$

$Area=18\sqrt{3}$

Therefore, the area of a rhombus is $18\sqrt{3}$ square units.
