The difference of 8 less a number n, multiplied by twelve, is equal to 3 more than the number.
which of the following equations can be used to find the missing number?
12(8 - n) = n +3
12(8 - n) + 3 =
12 (n - 8) =n+
12.8 - n +3=n

i belive those are the ones that are under 90 degreese.

(3x-8) or (3x+8)

step-by-step explanation:

step-by-step explanation: it is d

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)
