(3x² + 2xy + 4y²) + (6x² - 5xy + 3y²) + (9y² - 25y²)

Get rid of the parenthesis :)

3x² + 2xy + 4y² + 6x² - 5xy + 3y² + 9y² - 25y²

Add like terms.

(3x² + 6x²) + (2xy - 5xy) + (4y² + 3y² + 9y² - 25y²)

Simplify.

(9x²) + (-3xy) + (-11y²)

Get rid of the parenthesis.

9x² - 3xy - 11y²

~Hope I helped!~

Iteru [2.4K]

Answer:

12.5 kilograms

Step-by-step explanation:

Given:

Half of the granola served with breakfast.

Let the amount of Granola present initially = x kg

Half of it (\frac{x}{2}) served with breakfast, so remaining granola :

x-\dfrac{x}{2} = \dfrac{x}{2}

After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.

First of all, let us convert it to kilogram because the answer is required in Kilograms.

We know that:

1000 gms = 1 kilograms

1 gms = 0.001 kilograms

6250 gms  = 6250 \times 0.001 = 6.250 kilograms

Now, as per given question statement:

\dfrac{x}{2} = 6.250\ kg\\\Rightarrow x = 2 \times 6.250\\\Rightarrow \bold{x = 12.5\ kg}

So, the answer is:

Girl scout camp started with 12.5 Kilograms of granola.
