Which of the following is equivalent to (2x + 3)(2x + 3)?
Kryger [21]

Answer:

(2x+3)(2x+3)=4x^2+12x+9

Step-by-step explanation:

we are given

(2x+3)(2x+3)

Firstly, we will distribute it

=2x\times 2x+2x\times 3+3\times 2x+3\times 3

now, we can simplify it

=2\times 2\times x\times x+2\times 3x+3\times 2x+9

=4x^2+6x+6x+9

=4x^2+12x+9

so, we get simplified term as

(2x+3)(2x+3)=4x^2+12x+9

What is the sum of 3 consecutive integers of 87
Leviafan [203]
Hey there! Hello!

So, to set this problem up, all you need to do is imagine that the smallest number of these consecutive integers is x. The next two numbers will be x+1, then x+2, and that, altogether, will equal 87. In a problem, this will look like this:

x+x+1+x+2=87

All we need to do is solve for x! We can simplify the problem by combining like terms:

x+x+x+1+2=3x+3=87
3x+3-3=87-3
3x/3=84/3
x=28

Now that we know what x is, we can plug it into our original problem:

x+x+1+x+2 = 28+29+30=87

Hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)

Solve: 2x + 3 = -1<br> Please help me on this question :)
Nina [5.8K]

Answer:

<u>x=-2</u>

Step-by-step explanation:

the while goal of this is to isolate the x on one sideso x= the answer, so

first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you <u>x=-2.</u>

Which of the following is true for the rational function f(x) = x-16/x-4 ?
Ratling [72]
 <span>First of all, F is true because (16 - 16)/(16 - 4) = 0. It just means when you plug in that number (16) you'll get 0. This will NOT happen for 4 because the 0 is in the denominator. 

Look what happens if you have x = 4. This gives you 12/0, which is undefined. For some graphs, this is a hole, but let's look closer. 

What happens if you have x = 3.9? You'll have 12.1/0.1. 3.9999? 12.0001/0.0001. The closer you get to 4, the closer you'll get to y = infinity. 

But what if you have 4.1? 11.9/-0.1. You'll get the same results, but NEGATIVE infinity. So it is NOT a hole in the graph. 

If you draw it out, you'll see that there is a vertical asymptote at x = 4. 

B and F are true. 

As for horizontal asymptotes, look at it like this: y = 16-16/16 - 4 means y = 0. There is no asymptote here. Try subbing in 1 = (x -16)/(x - 4). 
Multiply by x - 4 on both sides 
x - 4 = x - 16 
There is no solution here; there will be an asymptote, so D is also true. 

B, D, and F are true. ,"yahoo answers"//////////////////if i get busted at least i put down my main source (you know what I'm saying)</span>

Image point B (4,-8) was transformed using the translation (x-2,y+3) what were the coordinates of B?
PilotLPTM [1.2K]
The coordinates of the image point are given to be B(4, -8). We are to find the coordinates of pre-image that is the coordinates before the translation.

The translation made was (x-2, y+3) 

This means, the x coordinate was moved 2 units to left and y coordinate was moved 3 units above. 

So, the coordinates of original point will be, 2 units to right of B and 3 units down of B.

So the coordinates will be (6, -11)
