What is (3x+6y-4)+2(x-6) simplified

Hi!

Explanation: First you had to remove parenthesis. Then it gave us 3x+6y-4+2 x-6. Next you can also expand 2(x-6): 2x-12 and it gave us 3x+6y-4+2x-12. Finally, you can simplify 3x+6y-4+2x-12: or 5x+6y-16. And the answer is =5x+6y-16 is the right answer. Hope this helps! And thank you for posting your question at here on . And have a great day! -Charlie

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)
