16! (x+4)(x+4)
You take half of the middle x value (half of 8x in this case). Half of 8 is 4, square that number (4) and you get 16!

I need to know the answer
grandymaker [24]

Answer: f(x)=-(x-5)^{2}(x+2)

Step-by-step explanation:

There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form f(x)=a(x-5)^{2}(x+2) for some constant a.

To find a, we can substitute the coordinates of the y-intercept, (0, -50).

-50=a(0-5)^{2}(0+2)\\\\-50=50a\\\\a=-1

So, f(x)=-(x-5)^{2}(x+2)

Cora sliced 18 \text{ kg}18 kg18, start text, space, k, g, end text of apples for a party. She divided the apple slices equally
Vikentia [17]

Answer:

Cora put 3600 apple slices in each bowl.

Step-by-step explanation:

Cora sliced 18 kg of green apples for a Party.

She divided the Apple slices equally between 5 large bowls.

We need to find how many grams of Apple slices did Cora put in each bowl.

Since,

1 kg = 1000 grams

18 kg = 18000 grams

To find how many grams of Apple slices did Cora put in each bowl, divide total apples by total no of bowls.

x=\dfrac{18000}{5}\\\\=3600

Hence, Cora put 3600 apple slices in each bowl.
