18. 9 x 0 = 0 S0, 9 + 0 + 9 = 18
x2+24x+144 = 9 x2+24x+144-9 = 0 x2+24x+135 = 0 (x+9)(x+15) = 0 x = -9 or x = -15
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
0=(9)2-(9-3)(root of 4)+3(2)
No, because it's a false statement. -9+0=-9 would be the identity property.
18. 9 x 0 = 0 S0, 9 + 0 + 9 = 18
It is: 9+0 = 9
the answer to 2+3+9+9+0=23 that is the professional way sio HA!!!!

-9 + 9 = 0 The equation can be written 9 - 9 = 0 The answer is 0 (zero)
Is this a trick-question? 1+0+0+8=9
It is: -9
9 + (-9) = 9 - 9 = 0
It is 0.
These numbers all add up to 81.
