Help with this graph please and thanks

i believe it's a.

i'm not sure on this one, most likely correct.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

60: 45 =12: 9 =4: 3 so the answer is 4: 3

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)
