Ineed so much on this question, every time i put an answer in it says it’s wrong and i don’t know why.

the winner was 1.4m/s quicker

Step-by-step explanation:

i think it is:

average speed= m:s

fay= 300: 50= 6m/s

tia= 300: 65= 4.6m/s

6-4.6= 1.4

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)
