Hannah and Andrea were selling tickets to the homecoming dance. They were set up in different locations, and while Andrea sold h number of homecoming tickets, Hannah sold 3h. What
information can we gather about the relationship between how many tickets Andrea sold and how
many Hannah sold?
Hannah sold 3
times more = tickets than Andrea.
If Hannah sold 66 tickets, how many did Andrea sell?

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
