<em>In Scientific Notation:</em>
China's current population is 1,355,692,544 while France only has 66,259,012. China has 1.29x10⁹ more people than the latter has. China is 0.20x10⁻² times greater in terms of population than France.
<em>In Mathematical sentence:</em>
China has over 1,289,433,532 people than France.
It is 20.46050044 times greater in population than France.
7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2 = 18x - 27 -24
15x + 2 = 18x - 51
+51 + 51
15x + 53 = 18x
-15x = -15x
53 = 3x
17.66 = x
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
If this is an option, it should be Similar Triangles.
