Answer:

n = 8.

Step-by-step explanation:

n^2 × constant nunber = W.

5^2 × constant number = 175. So the constant number is 7.

When W = 448, n^2 = W/7, n^2 = 64.

Thus, n = 8.

The point P(2k, k) is equidistant from A(-2, 4) and B (7,-5).<br>Find the value of k.<br>​
mario62 [17]

Answer:

k = 3

Step-by-step explanation:

Using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A (- 2, 4 ) and (x₂, y₂ ) = P (2k, k)

AP = \sqrt{(2k+2)^2+(k-4)^2}

Repeat

with (x₁, y₁ ) = B (7, - 5) and P = (2k, k)

BP = \sqrt{(2k-7)^2+(k+5)^2}

Given that AP = BP, then

\sqrt{(2k+2)^2+(k-4)^2} = \sqrt{(2k-7)^2+(k+5)^2}

Square both sides

(2k + 2)² + (k - 4)² = (2k - 7)² + (k + 5)² ← expand factors on both sides

4k² + 8k + 4 + k² - 8k + 16 = 4k² - 28k + 49 + k² + 10k + 25

Simplify both sides by collecting like terms

5k² + 20 = 5k² - 18k + 74 ( subtract 5k² from both sides )

20 = - 18k + 74 ( subtract 74 from both sides )

- 54 = - 18k ( divide both sides by - 18 )

k = 3

I need help finding the value
siniylev [52]

Answer:

17

Step-by-step explanation:

First, we notice that the triangle is isosceles . (In case you didn't know, the two tick marks on the sides of the triangle signify that they are congruent and have the same length.) Since the triangle is isosceles, we can apply the Base Angles Theorem.

The Base Angle Theorem states that the two angles opposite of the two congruent sides are also congruent. In this case, we can say that, because the angle measuring 29° and the third(top) angle are opposite to the two congruent sides, those two angles are congruent. Therefore, the third angle measures 29° as well.

Now that we know this, we can write the following equation:

29°+29°+(11x-65)° = 180.

Solving this equation, we have x = 17.

Hope this helps!
