Hello,

You can begin by putting the given zeros into factored form.
f(x) = (x + 2)(x - 5)(x - 6) 

Then, you can simplify the equation into standard form.
f(x) = x³ - 9x² + 8x + 60

Your final answer, in standard form, is f(x) = x³ - 9x² + 8x + 60.

Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. If x represents the numbe
masha68 [24]
The number of glasses is restricted to 44 cups. So the number of iced tea cups and the number of lemonade cups that she can serve is, maximum, 44. Then, if you call x the number of glasses of iced tea and call y the number of glasses of lemonade, you have that the total number of glasses (cups) is x + y. And <span>the equation that represents the number of glasses that she cacn serve is x + y = 44. You can place it in other equivalent ways, for example, solve for y: y = 44 - x. Those two equations are valid answers because they represent the same equation.</span>

Charra [1.4K]

Answer:

13C10 =286

Step-by-step explanation:

To solve this problem we must use the formula of combinations.

nCr =\frac{n!}{r!(n-r)!}

Where n is the number of players that there are and elect r of them

In this case there are 7 + 6 = 13 players and you choose 10 of them

Then we look for  13C10

13C10 =\frac{13!}{10!(13-10)!}

13C10 =\frac{13!}{10!*3!}

13C10 =286

There are 286 possible combinations
