the value of c that makes the expression a perfect square binomial is c=4 .
<u>Step-by-step explanation:</u>
Here we have , an expression x2 + 4x + c or ,
. We need to find the value of c that makes the expression a perfect square binomial. Let's find out:
We have , 
⇒ 
⇒ 
Now , we know that 
Comparing above equation , to
we get ;
⇒
{
}
⇒ 
⇒ 
Therefore , the value of c that makes the expression a perfect square binomial is c=4 .
First
we have to understand what the domain is. In a nutshell the domain is
the set of all x values that are represented in any given graph. In
this case we do not have a graph but we have the vertex. The x value
is 2, therefore: x
≥ 2.

hope this helps, Regards.
Answer:
See below in bold.
Step-by-step explanation:
If we add the 2 equations we eliminate x and we get 2y =2.
So y = 1.
Substituting y = 1 in the second equation 1 = x - 3.
So x = 4.
A. One solution: (4, 1).
If we drew a graph we would have 2 lines which intersect at the point (4, 1).

Answer:
Thus, option “c” 10% is correct.
Step-by-step explanation:
The percentage of students that like dubstep = 30%
The percentage of students that like trance music = 25%
The percentage of student that wants only house music = 20%
The percentage of students that like bot dubstep and trance = 15%
Now we have to find the percentage of students that like trance music but nor dubstep.
The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%
The percentage of students that like trance music but nor dubstep = 10%
Thus, option “c” 10% is correct.
