In the equation

, a is the initial amount and b is the growth factor. So our initial amount is 30 and our growth factor is 8.3. Your correct choice for this is A.
<span>The equation is not quadratic in for because it cannot be written as a second degree polynomial</span>
5/8=10×w this is my equation then i divide by 10 on both sides
w=6.25
A rectangle, is a quadrilateral with all angles at 90°.
a square is a quadrilateral with all equal sides, and right-angles all around.
now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.
