The perimeter of a triangle is when u add all of the sides together
(8x - 7w) + (2x + 6y) + (3y + 5w) =
10x + 9y - 2w is ur perimeter
8w + 12x - 9y
8w + 12x - 9y
8w + 12x + 5y
8w + 12x - 9y
the 1st, 2nd, and 4th answer choices are the same....so 3 of them are equal
Using the recursion equation, it is found that the value of the 2nd iterate is:
<h3>What is the recursive equation?</h3>
The value of the nth iteration is given by:
The initial estimate is:
Hence, the 1st iterate is given by:
The 2nd iterate is:
Thus, the fourth option is correct.

Answer:
130
Step-by-step explanation:
10 x 13 = 130
13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 = 130
100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)
