The answer is 0 obviously
57
x + 12x - 45 = 0 13x - 45 = 0 13x = -45 x = - 45/13 = -3.462 (rounded)
-45, 0, 45 and 45013590
you just cant only if u subtract 45-0=45
The discriminant is -199.
The question is incorrect since the mean of 45 57 0 and 3 is not 30. And the value of 45 is 45, whatever its mean when combined with other numbers. Similarly, the value of 57 is 57, whatever its mean when combined with other numbers; etc.
If you subtract 57 from 0 you get -57
199 is.
It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.It isn't. 45-45 = 0.

A - 24 = -24 A - 24 + 24 = -24 + 24 A - 0 = 0 A = 0

1. Divide number by 2, record the remainder. Repeat until you reach 0. 2. Re-write the remainders from bottom to top. 3. Check TEST -> ANS -> R 57/2 -> 28 -> 1 28/2 -> 14 -> 0 14/2 -> 07 -> 0 07/2 -> 03 -> 1 03/2 -> 01 -> 1 01/2 -> 00 -> 1 57 dec = 111001 bin Check: [1] [1] [1] [0] [0] [1] (1*25)+(1*24)+(1*23)+(0*22)+(0*21) +(1*20) 32 + 16 + 8 + 0 + 0 + 1 = 57
