Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.

X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2

X = [1 +/- sqrt(97)]/2

r is the rate of interest  

t is Number of Time Periods

Martin put 8 pounds of grapes into a bowl. Four friends each took 2/3 pounds from the bowl. What fraction represents the total a
charle [14.2K]
There are 8 pounds of grapes. Four people each take 2/3 out. We can find out how much was taken out by multiplying these four people by the amount they took out, 2/3:

\sf 4\times\dfrac{2}{3}=\dfrac{8}{3}

We can convert this improper fraction to a mixed number. Three goes into eight two times. 3 * 2 = 6. 8 - 6 = 2. So we have 2 and two thirds leftover, or:

\sf 2\dfrac{2}{3}

So the total amount of grapes that was removed from the bowl is \sf\dfrac{8}{3} or \sf 2\dfrac{2}{3} pounds.
