What is the sum of x2 + 4x – 2 and x2 + 5x + 6?

2x² + 9x + 4

Step-by-step explanation:

Sum of x² + 4x - 2 and x² + 5x + 6,

x² + 4x - 2 + x² + 5x + 6

⇒ 2x² + 9x + 4

answer: what are the answer choices?

step-by-step explanation:

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)
