L=n-2, W=4+L=n+2

A=LW, since L=n-2 and W=n+2 we have:

A=(n-2)(n+2) so it could be this expression or the expansion

A=n^2-4

The answer is 13. To solve this you have to do 4*3 which is 12. Then you subtract 25 and 12 to get an answer of 13.

Answer:

C

Step-by-step explanation:

$\sec( \alpha ) = \frac{1}{ \cos( \alpha ) } \\ \\ \sec( \alpha ) = \frac{1}{ \frac{ad}{hip} } \\ \\ \sec( \alpha ) = \frac{hip}{ad} \\ \\ \sec( \alpha ) = \frac{41}{40}$

Find the slope of the line that passes through the following points. Write "undefined" if the slope is undefined.

Katyanochek1 [597]

The slope of the line that passes through the following points is undefined

<em><u>Solution:</u></em>

Given that, We have to find the slope of line passing through two points

Given points are (-1, 5) and (-1, 6)

<em><u>The slope of line is given by formula:</u></em>

$m = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (-1, 6)$

<em><u>Substituting the values we get,</u></em>

$m = \frac{6-5}{-1-(-1)}\\\\m = \frac{1}{-1+1}\\\\m = \frac{1}{0}$

Thus the slope is undefined
