Answer:
Step-by-step explanation:
It would be X=2 because axis of symmetry is the line passing through X=2.
Answer:
14°
Step-by-step explanation:
Sum of angles is 180°
57 + 73 + (4x - 6) = 180
130 + 4x - 6 = 180
4x = 180 - 130 + 6
4x = 56
x = 14°
Answer: 2x+1
Notice how the 2x in the answer and the x, from x+6, multiplies to 2x^2
Also the 1 from the answer and the 6 from x+6 multiplies to 6
The results of 2x^2 and 6 are the first and last terms respectively of the original trinomial. None of the other answer choices fit this.
You can use the FOIL or box method to get
(x+6)*(2x+1) = x*(2x+1)+6*(2x+1)
(x+6)*(2x+1) = 2x^2+x+12x+6
(x+6)*(2x+1) = 2x^2+13x+6
which confirms the answer is 2x+1
