Please help me - A train is traveling from Washington, D. C. to Atlanta, Georgia. The total distance is 640 miles. So far, it has traveled 48% of the distance. Explain how to estimate how far the train has traveled. What is the estimated distance?

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)

true. i hope this ! go answer some of my newest

what are your numbers actually saying? they are spaced out.
