Do the opposite of division which is multiplication. 2.6x2=5.2
I hope I did it correctly and that it benefits you ^^
Answer: x-6
Explanation: x^2 is a DOTS, or difference of two squares. 36 is a perfect square and x^2 is a perfect square, and you are finding the difference. Therefore, you can do (x+6)(x-6). This works with any number. If there was x^2-16, it could be factored to (x+4)(x-4)
Mental way:
415 / 51.9 * 100 = 800 students in the school.
detailed way:
x is the amount of students in the school.
51.9% * x = 415
(divide both sides by 51.9% (or 0.519))
x = 800 students
The value of "x" is 
<em><u>Solution:</u></em>
Given f(x) = 4x - 6
g(x) = 8x + 4
<em><u>To find: value of x when f(x) = g(x)</u></em>
We can equate f(x) and g(x) as per given statement and solve for x
f(x) = g(x)
<em><u>Substituting the values of f(x) and g(x) in above expression,</u></em>
4x - 6 = 8x + 4
4x - 8x = 4 + 6
-4x = 10
On solving,
Thus value of "x" is
