Answer:
The solution is the <u><em>answer </em></u>or the number <u><em>behind the = sign</em></u>
EX::6x+4 (x=7) 6(7)+4=46....46 would be the <u><em>solution</em></u>
Since EF=FG, you can set 6x - 10 = to 3x + 11
![6x -10 = 3x +11](https://tex.z-dn.net/?f=6x%20-10%20%3D%203x%20%2B11)
Then add like terms
![6x - 3x = 11+10](https://tex.z-dn.net/?f=6x%20-%203x%20%3D%2011%2B10)
so,
![3x = 21](https://tex.z-dn.net/?f=3x%20%3D%2021)
Now you can divide by 3 to get
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
:)
then put it back into
![6x - 10](https://tex.z-dn.net/?f=6x%20-%2010%20)
![6(7) - 10 = EF](https://tex.z-dn.net/?f=6%287%29%20-%2010%20%3D%20EF)
so,
3•2-3•4
6-12=-30
-6=-30
false

Answer:
Length = 12 feet
Perimeter = 28 feet
Area = 24ft²
Step-by-step explanation:
You didn't ask a question so I don't know what the answer you want is so I assumed it was related to one of the answers shown above.
To calculate the length, you simply do 6*2
which is equal to 12.
The length is 12 feet.
However, if you want to find the perimeter:
12 + 12 + 2+ 2 = 28ft
If you wanted to find the area:
12*2 = 24ft²
I hope this helps!
