Hello!

f(x) = x² + 12x <=>

<=> a = 1, b = 12 <=>

<=> x = -12/2×1 <=>

<=> x = -6 <=>

<=> f(-6) = -36 <=>

<=> (-6; -36)

Good luck! :)

the legs of a right triangle have lengths of 28 meters and 21 meters. the hypotenuse has a lenght of 5x meters. what is the valu

Luba_88 [7]

From the Pythagorean Theorem, we know that a^2+b^2=c^2
28^2+21^2=(5x)^2
784+441=25x^2
1225=25x^2
49=x^2
x=7
The length of the hypotenuse would be 35m.

Yolanda filled 2liters bottles with water for a day at the park with her family. Her family drank 11.73 liters .How many liters

kotykmax [81]

Answer:

1.99 L

Step-by-step explanation:

In the question it is mentioned that

The total liters of the water filled is 2 liters

But the family drank 11.73 liters

How should it be possible that the family drank is more than the total liters

So here we assume that the family drunk water should be in milliliters

Now the number of liters left is

= 2,000 ML - 11.73 ML

= 1988.27 ML

Now convert into liters which is

= 1988.27 ÷ 1,000

= 1.99 L
