Lauren =l
David=d
Bethany's =x
Amanda =y
l=x+13
d=y+11
lx=2y
<span>(x+13)x=2y
</span>


or

(x-20)(l-20)=d
<span>(x-20)(x+13-20)=y+11 </span><span>
</span>



so I believe its b
Hope this helps :)
You need to use the cosine for this and this is how you do it.
Answer:
Player 1's position is Player 2's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.
Step-by-step explanation:
When you reflect a point (x, y) across the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign: it becomes (-x, y).
Thus, if a point P, say, (7,5) is reflected across the y-axis, its reflection P' becomes(-7,5)
