![x = - 4 \: or \: x = - 14](https://tex.z-dn.net/?f=x%20%3D%20%20-%204%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%2014)
Step-by-step explanation:
We have been given the equation
![(x + 9) {}^{2} = 25](https://tex.z-dn.net/?f=%28x%20%2B%209%29%20%7B%7D%5E%7B2%7D%20%20%3D%2025)
and we are asked to apply the square root property of equality to our given a equation and isolate the variable
First, take the square root of both sides of our equation
![\sqrt{(x + 9) {}^{2} } = \sqrt{25}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28x%20%2B%209%29%20%7B%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%5Csqrt%7B25%7D%20)
![x + 9 = \: 15](https://tex.z-dn.net/?f=x%20%2B%209%20%3D%20%20%5C%3A%2015)
![x + 9 = 5 \: or \: x + 9 = - 5](https://tex.z-dn.net/?f=x%20%2B%209%20%3D%205%20%5C%3A%20or%20%5C%3A%20x%20%2B%209%20%3D%20%20-%205)
![x + 9 - 9 = 5 - 9 \: or \: x + 9 - 9 = - 5 - 9](https://tex.z-dn.net/?f=x%20%2B%209%20-%209%20%3D%205%20-%209%20%5C%3A%20or%20%5C%3A%20x%20%2B%209%20-%209%20%3D%20%20-%205%20-%209)
![x = - 4 \: or \: x = - 14](https://tex.z-dn.net/?f=x%20%3D%20%20-%204%20%5C%3A%20or%20%5C%3A%20x%20%3D%20%20-%2014)

Answer:
![\frac{-13}{15} x-52](https://tex.z-dn.net/?f=%5Cfrac%7B-13%7D%7B15%7D%20x-52)
Step-by-step explanation:
![\frac{-5}{6}x-\frac{7}{30}x+\frac{1}{5}x-52](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B6%7Dx-%5Cfrac%7B7%7D%7B30%7Dx%2B%5Cfrac%7B1%7D%7B5%7Dx-52)
![=\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x+-52](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-5%7D%7B6%7Dx%2B%5Cfrac%7B-7%7D%7B30%7Dx%2B%5Cfrac%7B1%7D%7B5%7Dx%2B-52)
Combine Like Terms:

Therefore,
will be your final answer.
For any x in Real numbers, [x] is the greatest possible integer smaller than x, or equal to x if x is an integer.
According to this,
<span>[2.4] is the greatest integer , smaller than or equal to (so non greater) 2.4. This number is 2
similarly, </span>[-2.4] is the greatest integer , smaller than or equal to (so non greater) -2.4. This number is -3.
Answer:
A) <span>Because 2 is the greatest integer not greater than 2.4 and –3 is the greatest integer not greater than –2.4. </span>
