Answer:
1. Northwest 2. Southeast
Step-by-step explanation:
So, basically, here we have to compare two values. When we want to know how many times one value is bigger or smaller than the other one, we use division.
Here, we are given the value of average soil saturation in the entire county from the last year (0.24)and we want to compare it to this year's values.
First, we know that last year's value was 1.2 times greater than one of the region's this year. To find that value, the easiest thing to do is to divide:
0.24 / 1.2 = 0.2
That means that 0.24 is 1.2 times bigger then 0.2. Looking at this year's results we find that 0.2 was the saturation of NORTHWEST region.
For the second part of the question, we'll do the same thing. Now, last year's value was 0.25 of one of the region's this year. To find it, again we divide:
0.24 / 0.25 = 0.96
Again, looking at this year's results, we see that 0.96 was the saturation of SOUTHEAST region.
The product of a constant factor of four and a factor with the sum of two terms
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
c
=

.
Explanation:
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
So for
x
2
−
24
x
, dividing
−
24
by
2
gets us
−
12
.
Squaring
−
12
gets us
144
,
So
c
=
144
.
In general:
Consider the factoring identity
(
x
−
a
)
2
=
x
2
−
2
a
x
+
a
2
If we only have the middle term,
−
2
a
x
, then dividing the middle term by
2
x
gets us
−
2
a
x
2
x
=
−
a
(If we only take the coefficient on
x
, we do not have to divide by
x
.)
Then if we square that, we get
(
−
a
)
2
=
a
2
So as you can see, taking the coefficient on
x
, dividing it by
2
, and then squaring it will get us the magic constant that lets us complete the square.
