What is 2 times 3 times n times n = 54

kolezko [41]

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.

Find slope for 2x+5y=8?

Nitella [24]

First thing, you need to transform this equation to the form of y = ax + b

So you get:
2x + 5y = 8
5y = -2x + 8
$y = -\frac{2}{5} x + \frac{8}{5}$

In the form of y = ax + b, a is the slope.
In $y = -\frac{2}{5} x + \frac{8}{5}$ , you can see " $- \frac{2}{5} x$ ", and always the number before x is the slope
So, the slope of 2x + 5y = 8 is $- \frac{2}{5}$

Hope this Helps :)
