The solution set for -2x^2+12x=0

natita [175]

Answer:

{0,6}

Step-by-step explanation:

-2x^2+12x = 0

Factor out a -2x

-2x(x-6) =0

Using the zero product property

-2x = 0 and x-6=0

-2x = 0

Divide by -2

-2x/-2 = 0/-2

x=0

x-6=0

Add 6 to each side

x-6+6 =0+6

x=6

The solutions are 0 and 6

hram777 [196]

Answer:

She needs to buy 3 such containers.

Step-by-step explanation:

Mrs. Saledo wants to buy $1\frac{1}{2}$ quarts of whipping cream.

Now, $1\frac{1}{2}$ quarts = $\frac{3}{2}$ quarts = $\frac{3}{2} \times 2 = 3$ pints.

Since we know that 1 US liquid quart = 1 US liquid pints.

If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )
