Step-by-step explanation:
1,539 cups of flour. They sold 513 loaves and there are 3 cups of flour in each (523x3=1,539)
<span>y=-3x²-30x-27
Δ=b²-4ac=(-30)²-4.(-3).(-27)=900-324=576 ∴ √Δ=24
x'=(-b

√Δ)/2a=(-(-30)

24)/2.(-3)=-54/6=-9
x''=</span><span>(-b-√Δ)/2a=(-(-30)-24)/2.(-3)=-6/6=-1
Raízes são
x''=-9 e x''=-1</span>
