A=-2;b=9;c=9;
delta=b^2-4*a*c
root1=(-b+(delta^(0.5)))/(2*a)
root2=(-b-(delta^(0.5)))/(2*a)

delta =153
root1 = -0.8423
root2 = 5.3423

lisabon 2012 [21]

You multpily the length and the width to find the area of a shape. If the square is 3ft wide, then the square is also 3 ft long if the area is 9.
so, how tall is it?
3 ft. I meant rectangle. Its still the same for the height.

Create an equation for the following.

bixtya [17]

1/2x + 5 = 35

You use 1/2 because she sold half of her books . Then +5 because she gained 5 back and 35 because your end total should be 35.
