Answer:

3y(2x^{2} - 9x + 12y)

Step-by-step explanation:

Part A:

The GCF of 6, 3, 24, and 12 is 3:

so 3(2x^{2}y - xy - 8xy + 12y^{2})

= 3(2x^{2}y - 9xy + 12y^{2})

Also y is also common so:

= 3y(2x^{2} - 9x + 12y)

Part B:

3y(2x^{2} - 9x + 12y)

Suppose an egg is thrown off the top of a building 240 feet above ground. The height, h, in feet of the rock above the ground is
Nostrana [21]
<h2>Hello!</h2>

The answer is: D) 6.2 seconds

<h2>Why?</h2>

When the egg hit the ground,  the height will be equal to 0, so, from the given equation we need to find the roots or zeroes.

It's a quadratic function, we can find the roots using the quadratic equation:

\frac{-b+-\sqrt{b^{2}-4ac}}{2a}

So, from the given function we know that:

a=-16\\b=60\\c=240

So, substituting we have:

\frac{-60+-\sqrt{60^{2}-4*(-16)*240}}{2*(-16)}=\frac{-60+-\sqrt{3600+15360}}{-32}\\\\\frac{-60+-\sqrt{18960}}{-32}=\frac{-60+-(137.69)}{-32}

x1=\frac{-60-137.69}{-32}=6.18

x2=\frac{-60+137.69}{-32}=-2.42

So, since the time can not be a negative value, the correct option is:

6.18≈6.2 seconds

Hence, it takes 6.2 seconds to the egg to hit the ground.

Have a nice day!
