Solve for x. show each step 4.5(4−)+36=202−2.5(3+28)

Distribute the 2.5 then solve what's in the parentheses and solve the rest of the right side then distribute 4.5, solve then divide the number with the x on both sides.

4.5 ( -4) = -18 & -2.5(3+28)=-77.5

= -18 + 36 = 202 - 77.5  

Solve!

 18 = 122.5

18÷18=0

122.5÷18=6.08

6.08

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)
