X = √63
b = sqrt32 or 4 root 2
.12
Using the quadratic equation formula: x = 8.42 or x = -1.42
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
4 squared plus 4 squared divided by 4 plus 4
12
12 squared.
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
Twelve squared is a dozen dozen, or one gross. 122 = 12 times 12 = 144
12 + 5 equals...
