Answer:
-5-2i
Step-by-step explanation:
Its already simplified
F(x) = 3x ; where x is the number of books purchased.

I saw this problem and the instruction was to graph the function and show the domain and range.
The domain is all the x-values while the range is all the y-values.
A = pi(r^2)
1. Calculate radius:
r = d/2, so r = 18
2. Enter variable into equation
a = pi(r^2)
becomes a = 3.14(18^2)
3. Solve
a = 3.14(324)
a ~= 1018 in2
4. Convert to feet
1018/12 = 84 ft2
5. Multiply by unit rate
84(3.5) = $294
It will cost $294 to paint the sign.

40/8 is 5. You can check this by multiplying 8 and 5 and seeing if it equals 40. Also, if you look at 40/8 as a fraction you can simplify it. 40/8=20/4=10/2=5/1=5
