The answer is ERROR i tried it by hand and by calculator and both answers ended up as ERROR
Answer:
- table: 14, 16, 18
- equation: P = 2n +12
Step-by-step explanation:
Perimeter values will be ...
rectangles . . . perimeter
1 . . . 14
2 . . . 16
3 . . . 18
__
The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...
P = 2(6 +n) = 12 +2n
Your equation is ...
P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.
_____
<em>Additional comment</em>
You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...
y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles
Each face has a chance of 1/6
So you beed 6 rolls
This is a simple Pythagoras' theorem problem. If the length of the right angled triangle is 15ft and its width is 8ft, then its hypotenuse (x, the diagonal or the length of the pipe in this case) will be:

Therefore, your answer is B. The length of the pipe will be 17 feet.
