Answer:

Step-by-step explanation:
We know that a rational number cannot have roots. All of the answer choices cannot be simplified except for
, which can become 1. Therefore, our answer is
.
Uh can you show the problems? Because I wouldn’t be able to answer your question if you don’t show me the expressions
The answer is 3x^2-19x+1
(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1
Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1
The simplified expression is 6+3i
Answer:
a=22.6549
Step-by-step explanation:
Calculated based on 2 given angles and 1 given side.
∠C = 180° - A - B = 0.99484 rad = 57°
a = c·sin(A)/sin(C) = 22.6549
b = c·sin(B)/sin(C) = 12.33874
