Answer:
u = 1.5
Step-by-step explanation:
5+4u=11
-5 -5
4u = 6
/4 /4
u=1.5
tis always a good idea when factoring to start off with a quick prime factoring.

All I can help with is that the very bottom left angle is 60 degrees

Answer:
100.26
Step-by-step explanation:
You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.
This is what that would look like:
1. Divide 6 (the diameter) by 2 because ![r=\frac{1}{2} d](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B1%7D%7B2%7D%20d)
![r=\frac{1}{2} 6](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B1%7D%7B2%7D%206)
![r=3](https://tex.z-dn.net/?f=r%3D3)
2. plug into the formula ![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
![A=\pi 3^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%203%5E%7B2%7D)
3. square the 3
![A=\pi 9](https://tex.z-dn.net/?f=A%3D%5Cpi%209)
4. multiply 9 by 3.14 (pi)
![A=28.26](https://tex.z-dn.net/?f=A%3D28.26)
This means the area of both the semi circles added together would equal 28.26
Then you would use the formula
to find the area of the rectangle
1. plug in the numbers given
· ![6](https://tex.z-dn.net/?f=6)
2. solve
![A=72](https://tex.z-dn.net/?f=A%3D72)
Then add the area of the semicircles to the area of the rectangle
![A=28.26+72](https://tex.z-dn.net/?f=A%3D28.26%2B72)
to get the area of the entire figure:
![A=100.26](https://tex.z-dn.net/?f=A%3D100.26)
