Which of the following equations has the same solutions as x^2+8x+2=0

Mathematics

7 0

Answer:

See below

Step-by-step explanation:

Need the choices.....

     essentially,  you can multiply this equation  by any constant to get an equivalent equation with the same solutions.

x^2 + 8x + 2 = 0      multiply both sides by '3' to get

3x^2 + 24 x + 6 = 0     <===== this will have the same solutions

    or this one:

x^2 + 8x + 2  = 0            Multiply both sides by   '6' to get

6x^2 + 48x + 12 = 0      <===== this will have the same solutions also

etc....

What is the surface area of a rectangular prism?<br><br>length : 3<br>width : 3<br>height = 5
elixir [45]
Since it is a rectangular prism, the front and back are the same. the sides are the same and the top and bottom are the same. You would find the area of the front and back first. Since they both have the same measurements, you can find the area of one of the faces and multiply by 2.
A=BH
A= 3x5
A=15
15x2=30
So the front and back's area is 30. Now you find the area of both sides. They are both rectangle so the formula is A=BH.
A=BH
A=3x5
A=15
15x2=30
Now you find the area of the top and bottom. It is also a rectangle so you will use the same formula.
A=BH
A=3x3
A=9
9x2=18
Finally, you add all these measurements together adn that is the surface area. 
This surface area of this rectangle prism is 78.

Help me please I’m so confused ):
Marrrta [24]
The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.

A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.

So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.

The domain is everything BUT those two values, because they essentially break your function.

I really need some help
defon

Answer:

405,376

Step-by-step explanation:

the question is worded weirdly.

Its saying 37,700 copies were sold in one month and then that amount is 9.3% of books sold to date. So, its saying that 37,700 is only 9.3% out of 100%. To get the hundred i devided 37,700 into 9.3 to see how much 1% is. then i multiplied that by 100
