X2+2x-15=0
2x+2x-15=0
4x-15=0
4x=15
so answer is x= 15/4
When countries are at war, the general rule is that civilians should not be targeted and I <u>support </u>this notion.
<h3>The Concept of War</h3>
- War is fought by nations to assert dominance and achieve certain conditions.
- War is fought by soldiers who pick of weapons to engage in war.
Civilians should therefore not be targeted because they have not picked up weapons to engage in the fight and so cannot be said to be targets. It makes no sense to leave the person you are fighting and who wants to fight you, to fight those who are not interested in fighting.
In conclusion, civilians should not be targeted.

Answer:</h2>
Shown below
<h2>
Step-by-step explanation:</h2>
This function represents greatest integer function, which is the most famous of the step functions, which is denoted by ![[x]](https://tex.z-dn.net/?f=%5Bx%5D)
. So, this function is defined as:
![f(x)=[x] \ the \ greatest \ integer \ less \ than \ or \ equal \ to \ x.](https://tex.z-dn.net/?f=f%28x%29%3D%5Bx%5D%20%5C%20the%20%5C%20greatest%20%5C%20integer%20%5C%20less%20%5C%20than%20%5C%20or%20%5C%20equal%20%5C%20to%20%5C%20x.)
. The graph of the greatest integer function has the following characteristics:
a) The domain of the function is the set of all real numbers.
b) The range of the function is the set of all integers.
c) The graph has a 
at 
and 
in the interval 
d) The graph is constant between each pair of consecutive integers.
e) The graph jumps vertically one unit at each integer value.
![f(x)=[x]-3](https://tex.z-dn.net/?f=f%28x%29%3D%5Bx%5D-3)
tells us that the original function has been shifted 3 units downward. So the correct option has been marked in the square red below.
Perimeter=2l+2w
28=2l+2w
l=w+2
Substitute for l
28=2(w+2)+2w
28= 2w+4+2w
28=4w+4
24=4w
6=w
Plug the w value in
l=6+2
l=8
Final answer: Length=8 ft, Width=6 ft
