<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

What is (2x² + 9x + 7) = (x + 1) ?

<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

2x² + 9x + 7 = x + 1

2x² + 9x - x + 7 - 1 = 0

2x² + 8x + 6 = 0

2(x² + 4x + 3) = 0

x² + 4x + 3 = 0

x² + 3x + x + 3 = 0

x( x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

So, option (D) x + 1 is correct. [Answer]

Blababa [14]

Answer: V = 100\pi in^{3} (third option)

Given Information:

  • V = \frac{1}{3}\pi r^{2} h <-- volume formula.
  • r = 5
  • y = 13
  • <em>h = ?</em>

To find h...

  • h, r, and y make a right triangle.
  • h and r are the two legs, y is the hyptenuse.
  • h^{2} + r^{2} = y^{2}
  • h^{2} + 5^{2} = 13^{2}
  • h^{2} + 25 = 169
  • h^{2} = 144
  • h = 12

Use formula:

  • V = \frac{1}{3}\pi r^{2} h
  • V = \frac{1}{3} \pi (5)^{2} (12)
  • V = \frac{1}{3} \pi (25)(12)
  • V = \frac{1}{3} \pi (300)
  • V = 100\pi
