What is the solution to this equation? -8x + 4 = 36
A. x= -5
B. x= 4
C. x = 5
D. x= -4.

D. x= -4

Step-by-step explanation:

-8x × -4 = 32 + 4 = 36

you can subtract 4 from 36, which leaves you with -8x = 32.  you then divide 32 by -8 to (1) cancel out -8 which will leave you with x, and (2) give you your answer.  32 / -8 = -4.

x is -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)
