Answer:
The correct answer is -9.2h
Yes the greatest common factor of odd numbers will always be odd
5x^2 + 7x = 6
5x^2 + 7x -6 = 0
5x^2 + 10x -3x -6 =0
5x × (x + 2) -3 (x + 2) = 0
(x + 2) × (5x - 3) = 0
x + 2 = 0
5x - 3 = 0
x = -2
x = 3/5
answer: x = -2, x = 3/5
2/5 would be closer
since 2/5 is 0.4
and 1/3 is 0.333...
You can draw a number line to see how 2/5 ( 0.4) is closest to 0.39
