Answer:
(f • g)(3) = 186
Step-by-step explanation:
The area of a rectangle is (length)(width).
Here, (length) = x + 3 and (width) = 12x - 5, and so the area as a function of x is
(f • g)(x) = (x + 3)(12x - 5) = 12x^2 - 5x + 36x - 15.
This simplifies to:
(f • g)(x) = (x + 3)(12x - 5) = 12x^2 + 31x - 15.
Evaluating this function at x = 3, as instructed, we get:
(f • g)(3) = (12)( - 5) = 12(3)^2 + 31(3) - 15.
Carrying out the indicated operations, we get: 108 + 93 - 15, or
(f • g)(3) = 186
Answer: Candice has $51.93 left after going to the store

Answer:
6 miles north and 3 miles west
Step-by-step explanation:
If you picture these miles on a graph, you start at (0,0). Then you go 8 miles south (0, -8). Then 3 miles east (3, -8). Finally, 2 miles north (3, -6). You are 3 miles east and 6 miles south, so you go the opposite directions.
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75
