Answer:
24 ways
Step-by-step explanation:
Given that
Number of students = 4
Lecturer have to stand in the middle position.
We have five places in which middle place is for lecturer,now we have four places and we have to arrange four students on that four places.So there will 4! ways to arrange those students.
4!= 4 x 3 x 2 x 1
4! =24
So we have 24 ways to arrange 4 students and one lecturer .
Linear equations in one variables shows always graph in straight line,
For ex: x = 3, y = 4, x = -1.5, y = -2/3
Also two variables linear equations with degree of 0 or 1 (Each term) shows always graph in straight line,
For ex: x + y = 5, 2x - 4y = 7 etc.

Answer:
y = 4
Step-by-step explanation:
Plug 3 in for 'x' in the equation and solve for 'y'...
8(3) - 3(y) = 12
24 - 3y = 12
-3y = -12
y = 4

<h2>Solving the Question</h2>
We're given:
In a trinomial, we're given the 
and 
values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:
Therefore, the term that we can add is + 4.
To write this as the square of a bracketed expression, we can follow the rule
