ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

<u><em>Explanation</em></u>

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need x cups of rice for making 10 servings of casserole.

Now, the equation according to <u>the ratio of "cups of rice" to the "servings of casserole" </u>will be.....

\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....

So, you will need 3.333.... cups of rice to make 10 servings of casserole.

Hitman42 [59]

Factor the polynomial: – x3 - 4x2 - 5x
Alinara [238K]

Answer:

-x3-4x2-5x=-x(x^2+4x+5)

Step-by-step explanation:

we are given the polynomial as

-x3-4x2-5x

here we can see that the GCF of -x^3 , -4x^2 and -5x is

-x

Hence we take it outside the bracket

-x(x^2+4x+5)

The polynomial within the bracket x^2+4x+5 can not be factorized further , hence this would be our final answer.
