Indicate which property is illustrated in Step 3. Step 1 4x + 2 + 7x + 5 = (4x + 2) + (7x + 5)
Step 2 = 4x + (2 + 7x) + 5
Step 3 = 4x + (7x + 2) + 5
Step 4 = (4x + 7x) + (2 + 5)
Step 5 = (4 + 7)x + (2 + 5)

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)
