Answer:
x= 3 and x= -3
Step-by-step explanation:
x^2 -9 = 0
Factor x^2-9
(x+3)(x-3)
If x+3=0, then x= -3
If x-3=0, then x= 3
Let's solve this by using the quadratic formula:

Note that we only use the coefficients so a=12, b=-14, and c=-6.
Plug values in the quadratic equation:

And so by evaluating those values we obtain:

Now we have two answers which are our factors one where we add another where we subtract and so:
First factor:

Second Factor:

And so your factors are

meaning that those are your roots/x-intercepts.
Answer:
62.77 million gallons
Step-by-step explanation:
Given,
The function that shows rate of leaking oil per minute in after t hours,

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,
Hence, the quantity of oil leaked out in the first 3 hours,



![=0.7[tan^{-1}(t)]_{0}^{180}](https://tex.z-dn.net/?f=%3D0.7%5Btan%5E%7B-1%7D%28t%29%5D_%7B0%7D%5E%7B180%7D)


= 62.77 million gallons

My answer is much too big for those choices.
So, I'm guessing that 16 meters is the diameter.
If that's the case, radius = 8 meters and
Cylinder Volume = 3.14 * 8^2 * 24
<span>Cylinder Volume = 3.14 * 64 * 24

So answer is "c"
Answer:
x=4y+1
Step-by-step explanation:
3x−7=12y−4
Step 1: Add 7 to both sides.
3x−7+7=12y−4+7
3x=12y+3
Step 2: Divide both sides by 3.
3x
3
=
12y+3
3
x=4y+1
