Answer:
B 12.68
Step-by-step explanation:
you will need to find the distance between each segment-
so the length of DC, CF, FE, ED

DC:
D(-2,-1) C(-1,2)

CF:
C(-1,2) F(1,1)

FE
F(1,1) E(2,-2)

ED
E(2,-2) D(-2,-1)

3.16+2.24+3.16+4.12= 12.68
Answer:
possible. it's a scalene triangle, an angle with different lengths
Answer:

Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:

Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":

Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:

Answer: 7
Step-by-step explanation:

You can either remove brackets and just do a little addition and subtraction.


So the answer is 7.
Or just finish things inside the brackets first.

So the answer is 7.
The answer is x is less than or equal to 3. the first answer choice
