Factor completely<br> B. (x+5)²-2(x+5)-24<br> C. (x+2)²-8(x+2)+15<br> D. 2(2x-1)²-9(2x-1)+4
Sladkaya [172]
B.
{x}^{2} + 10x + 25 - 2x - 10 - 24 = \\ x {}^{2} + 8x - 9 = \\ (x - 1)(x + 9)

C.
{x}^{2} + 4x +4 - 8x - 16 + 15 = \\ x {}^{2} - 4x + 3 = \\ (x - 3)(x - 1)
D.
2( {4x}^{2} - 4x + 1) - 18x + 9 + 4 = \\ 8x {}^{2} - 8x + 2 - 18x + 13 = \\ 8x {}^{2} - 26x + 15

X= <br> Y=<br> Find the values of X and Y
Art [367]
<h3><u>Answer:</u></h3>
  • x = 50°
  • y = 65°
<h3><u>Step-by-step explanation:</u></h3>

<u>We can clearly see that the triangle is an isosceles triangle. This also means that y must equal to 180 - 115. Let's solve.</u>

  • => x + y + 180 - 115 = 180
  • => x + y + 65 = 180

<u>Since 180 - 115 equals 65, this means that </u><u>y = 65.</u>

  • => x + 65 + 65 = 180
  • => x + 130 = 180
  • => x = 180 - 130
  • => x = 50
<h3><u>Conclusion:</u></h3>

<u>Therefore, our answers are:</u>

  • x = 50°
  • y = 65°

Hoped this helped.

What is the answer for r if the equation is
Vlad [161]

9514 1404 393

Answer:

  r = √(V/(πh))

Step-by-step explanation:

To solve for r, "undo" what has been done to r. The "undo" is generally in the reverse order. Here, we have ...

  • r is squared
  • the square is multiplied by πh

To undo these operations, we ...

  V/(πh) = r² . . . . . . . . divide by πh

  √(V/(πh)) = r . . . . . . take the square root

  r = √(V/(πh))
