The diagonals of a parallelogram are congruent
The length WY is 32
<h3>How to determine the length WY</h3>
Given that:
and
Then, we have:
diagonal
Subtract x^2 from both sides
Divide both sides by -6
The length WY is calculated as:
So, we have:
![WY=2 * [x^2 - 48]](https://tex.z-dn.net/?f=WY%3D2%20%2A%20%5Bx%5E2%20-%2048%5D)
Substitute 8 for x
![WY=2 * [8^2 - 48]](https://tex.z-dn.net/?f=WY%3D2%20%2A%20%5B8%5E2%20-%2048%5D)
Simplify
Hence, the length WY is 32

Answer:
option 2
Step-by-step explanation:
Answer:
(B)
4 +/- 3 sqrt(2) or 4+3sqrt(2) and 4-3sqrt(2)
Step-by-step explanation:
4(c-4)^2=72
4(c-4)(c-4)=72
foil the parenthesis (first, outside, inside, last)
4(c^2 -4c -4c +16)=72
4(c^2-8c+16)=72
divide each side by 4
c^2-8c+16=18
subtract 18 from both sides
c^2-8c-2
use quadratic formula
((-b +/- sqrt((-b^2)-4ac)))/2a
((-(-8)+/-sqrt((-8)^2-4(1)(-2)))/2(1))
(8+/-sqrt(64-(-8)))/2
(8+/-sqrt(64+8))/2
(8+/-sqrt(72))/2
(8+/-sqrt(36 * 2))/2
(8+/-6sqrt(2))/2
4+/-3sqrt(2)
or 4+3sqrt(2) and 4-3sqrt(2)
So you have to find 15 percent of 900 which would be 135
