The quadrants in which all the coordinates given are located is; As explained below.
<h3>How to Identify Quadrants in coordinates?</h3>
1) (2, 4) is located in Quadrant I where both x and y-values are positive.
2) (0, -3) is located in Quadrant II where x - values are positive but y-values are negative.
3) (-1, 1/2) is located in Quadrant IV.
4) (-2 1/2, -7) is located in Quadrant III where x and y values are both negative.
5) (0, 6) is located in Quadrant I where both x and y-values are positive.
6) (-5, 0) is located in Quadrant IV where x is negative but y is positive.

Simple..
there is a major difference between 6z and
6z means: 6 times z
and
means: z to the power of 6(z*z*z*z*z*z)
An example...
make z=2...plug n chug..
6z----> 6(2)=12
and
--->
=64
As you can see..there is a
major difference.
Thus, your answer.

<span>Borders are interesting because you have to remember that you have to pave the 4 corners.
.
The area of the garden = 12*16 = 192 square meters.
.
Then you add the border with width 'x'.
So,
Length is now L + 2x
Width is now W + 2x
.
We are told:
(L+2x)(W+2x) = 285
.
(12+2x)(16+2x) = 285
.
192 +24x +32x +4x^2 = 285
.
4x^2 + 56x + 192 = 285
.
4x^2 + 56x - 93 = 0
.
<span><span>Solved by pluggable solver: SOLVE quadratic equation with variable</span><span>Quadratic equation (in our case ) has the following solutons:
For these solutions to exist, the discriminant should not be a negative number.
First, we need to compute the discriminant : .
Discriminant d=4624 is greater than zero. That means that there are two solutions: .
Quadratic expression can be factored:
Again, the answer is: 1.5, -15.5. Here's your graph:
</span></span>
.
You cannot have a negative width, so the border is 1.5 m.
.
Always check your work.
L = 12 + 2(1.5) = 15
W = 16 + 2(1.5) = 19
15*19 = 285
Correct.
.
Answer: The border is 1.5 meters wide.
