The square below has an area of x^2+4x+4 square meters.
What expression represents the length of one side of the square?

Area (A) = side^2

Side = √A

If area is x^2 + 4x + 4, length of one side will be

Root of (x^2 + 4x + 4)

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
