If 20+2(3x+10)=2x-3(3+x) what is the value of x? pls answer

20 + 2 ( 3x + 10 ) = 2x - 3 ( 3 + x )
 20  +   6x    + 20  =  2x   -9   - 3x
        80 + 6x          =   -1x  - 9
        80  +   9         = -6x  - 1x
               89            =      -7x
             - 12.71       = x
hope it help

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4

Your answer should be 1/3. i hope i could ! good luck : )
