Answer: f(10) = -19
Step-by-step explanation:
1. Plug 10 into n
f(10) = -2(10) + 1
2. Multiply 10 by -2
f(10) = -20 + 1
3. Addition
f(10) = -19
-.1666666666 is the reciprocal of -6
The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
