What number should be added to both sides of the equation to complete the square x^2+3x=6
Allisa [31]
Take half of the coefficient of x:  It is 3, and half that is 3/2.


Then   <span>x^2+3x=6  becomes:

</span><span>           x^2+3x + (3/2)^2 =6 + (3/2)^2, and

             (x+3/2)^2 = 6 + 9/4

You were not asked to solve the equation, but why not do it for the practice?

</span>Solve (x+3/2)^2 = 6 + 9/4 for x.  There will be 2 values.

Find the volume of a pyramid with a square base, where the perimeter of the
lianna [129]

Answer:

42.7\,\,cubic\,\, meters

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = 4(side\,\,of\,\,a\,\,square)

side of a square = \frac{12.8}{4}=3.2\,\,m

Area of a square (A) = (side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = \frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters

I need help ASAP help me plzzzzzz
anzhelika [568]
The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))
