You would add 6+3 which equals 9 and then you would divide 111/9 and you get 12.33333...

Hi lovely,
The answer you're looking for would be 76.7
.59x130 = 76.7
9x + 2 = 3x - 10
<u>-3x -3x </u>
6x + 2 = -10
<u> -2 -2</u>
<u>6x</u> = <u>-12</u>
6 6
x = -2
3(x - 2) = -2(x + 3)
3(x) - 3(2) = -2(x) - 2(3)
3x - 6 = -2x - 6
<u>+2x +2x </u>
5x - 6 = -6
<u> +6 +6</u>
<u>5x</u> =<u> 0</u>
5 5
x = 0
the area of the square is
(3x +2)(3x+2)
