(07.06 MC) Choose the correct simplification of (5x − 6)(3x2 − 4x − 3). (5 points) Select one: a. 15x3 − 38x2 + 9x − 18 b. 15x3 + 38x2 − 9x + 18 c. 15x3 − 38x2 + 9x + 18 d. 15x3 + 38x2 − 9x − 18

the answer is a beach is the best place to be

the answer is a.

135 and 80

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)
