Harun is designing a room addition for a home and wants a rectangular window with area that is more than 12 square feet but not more than 24 square feet. harun knows he wants the window to be 4 feet wide. find an inequality to find the length for x.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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)
