If I'm reading this correctly, it is 2*3*n*n = 6n^2
6n^2 = 54 Divide by 6
n^2 = 54/6
n^2 = 9 Take the square root of both sides.
sqrt(n^2) = sqrt(9)
n = +/- 3
n = + 3 or n = -3. Both will solve the equation above.
Edit
2 * 3 * n * n
Let n = 3
2 * 3 * 3 * 3 = 6 * 9 = 54
The other value is n = - 2
2 * 3 * n * n
2 * 3 * (-3) * (-3) A minus times a minus is a plus.
2 * 3 * 9 = 6 * 9 = 54
both + 3 and - 3 for n will give 54.
Here is your answer > >
Width of rectangle =15 inches
Length of rectangle =?
Diagonal of rectangle = 25 inches
We know that
(Diagonal of rectagle)^2=length^2+breadth^2
(25)^2=l^2+(15)^2
625=l^2+225
l^2=625-225
l^2=400
l=Root 400
l=20 inches
Hope it helps!
