A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.
nlexa [21]
To find the length of a line given two points, we are going to use the distance formula, which is defined below:

(
and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

- Substitute values into formula

- Combine like terms and then simplify
to 0

- Compute


- Compute

The length of DC is 3.
there are 6 terms! hope this helped
Answer:
Divide the weight of the bag by 2.
Step-by-step explanation:
Every time we divide the weight of bags by 2 we always get the number of marbles in this situation.
For example, in the first one:
Weight of bag is 20
Number of marbles is 10
20/10 = 2 or 20 / 2 = 10
On bag number 5 the weight is 100 grams (Add 20 every time)
100/2 = 50
The number of marbles in a bag that weighs 100 grams is 50.
50 marbles
You put all x on left side and numercial on the right side
13x-12x = 4+4
x = 8
