Answer:
211 cm
Step-by-step explanation:
upper rectangle + lower rectangle (11-8=3) + end triangles
(8x20) + (3x12) + (1/2x3x5 each x2)
160+36+15=211
The value of
is 4.
By Geometry, we know that line segment
, which is equivalent to:
![DF = 3\cdot x + 2 + x + 5](https://tex.z-dn.net/?f=DF%20%3D%203%5Ccdot%20x%20%2B%202%20%2B%20x%20%2B%205)
(1)
Now we solve algebraically the resulting expression.
If we know that
, then we solve the equation for
:
![4\cdot x + 7 = 23](https://tex.z-dn.net/?f=4%5Ccdot%20x%20%2B%207%20%3D%2023)
![4\cdot x = 16](https://tex.z-dn.net/?f=4%5Ccdot%20x%20%3D%2016)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
The value of
is 4.

Well the solution to this problem is x < -4
Answer:
x = 12
Step-by-step explanation:
IMPORTANT: Both answers should add up to 180 if they dont you did it wrong!
(10x - 20) + (6x + 8 ) = 180 plug in 12 for both of them
(10 * 12 - 20) + 6 * 12 + 8) = 120
(120 - 20) + (72+ 8 ) = 180
(100) + (80) = 180
so x = 12
