PLZ HELP! Determine the value of k. Round your answer to the nearest hundredth if necessary.

correct answers below:

he answer is x=1x3 because x=1 to x=3

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

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)
