9f-11-(14f+4)=0
9f-14f-4-11=0
add all the numbers together, and all the variables
-5f-15=0
We move all terms containing f to the left, all other terms to the right
-5f=15
f=15/-5
f=-3

Step-by-step explanation:
Answer:
388
Step-by-step explanation:
We need to find the area of the semicircle and parallelogram separately and then combine.
The formula for the area of a semicircle is 1/2(pi*r^2)
r = 12. 12^2 = 144
1/2(pi*144) = 226..1946711 which we can just round to 226
The formula for the area of a parallelogram is bh
b = 18, h = 9. 18*9 = 162.
226+162 = 388
