4x^2+6x=12
16x+6x=12
22x=12
x=12/22 or 0.55

The said triangle that is asked is a right triangle which has a proportion on each angle of 3 and 6. These proportions are the angles, which is 45, 45, and 90, which also means that the two rays of the triangle are the same and proved that ab= ac that makes the angle a is a 90 degree in value.
600 x 5 x i = 60
3000 i = 60
i = 60 / 3000
i = 0.02
0.02 = 2%
answer <span>the interest rate was</span> 2%
