- 58 ≠ 57
- No
#8
- 11² + 2² = 121 + 4 = 125
- (5√5)² = 25*5 = 125
- 125 = 125
- Yes

and ywww
There would be 1 real zero and two complex zeros
I'm pretty sure it's 28 but sorry if I'm wrong it might be 44
Answer:
x = -27
Step-by-step explanation:
4x+27=3x
Subtract 3x from both sides of the equation.
==> 4x + 27 -3x = 3x - 3x
==> 4x - 3x + 27 = 0
==> 1x + 27 = 0
Subtract 27 from both sides,
==> x + 27 - 27 = 0 - 27
==> x = -27
