Answer:

C. {-9,-3}

Step-by-step explanation:

|k+6|=3 gives k+6=3 if k + 6 \geq 0. This gives k=-3, which is valid.

It can also give -(k+6) = 3 if k + 6 < 0. This gives k=-9, which is valid.

Hence the solutions are k=-9 \vee k=-3.

Find the missing side lengths. Answers are in simplest radical form with the denominator rationalized
Roman55 [17]

Answer:

Option B.

Step-by-step explanation:

The given triangle is a right angle triangle.

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

In the given triangle,

\tan (45^{\circ})=\dfrac{v}{7}

1=\dfrac{v}{7}

7=v

Using Pythagoras theorem, we get

hypotenuse^2=Perpendicular^2+Base^2

u^2=v^2+7^2

u^2=7^2+7^2

u^2=2(7^2)

Taking square root on both sides, we get

u=\sqrt{2(7^2)}

u=7\sqrt{2}

Therefore, the correct option is B.
