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.
The sale price of the coats is 160% of the purchase price of the coats.
<u>Step-by-step explanation:</u>
The owner buys the coats at a purchase price= $60
He sells the coats for a selling price= $96
Now, the question is:
The selling price $96 is what percentage of the purchase price $60
<u>step 1</u>: 96= x% of 60
<u>step 2</u>: 96= (x/100)*60
<u>step 3</u>: 96= 6x/10
<u>step 4</u>: 960/6 = x
<u>step 5</u>: x = 160%
