Answer: -6
-6•-7=42
Negative times a negative equals a positive
P=2L+2W
P-2W=2L
P/2-W=L
L=P/2-W
The slope of <em>y</em> = 2<em>x</em> - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points <em>A</em> and <em>B</em> is also 2. This means
(8 - 4) / (6 - <em>n</em>) = 2
Solve for <em>n</em> :
4 / (6 - <em>n</em>) = 2
4/2 = 6 - <em>n</em>
2 = 6 - <em>n</em>
<em>n</em> = 6 - 2
<em>n</em> = 4
-mn^2-5m^2/(5m-2)(m+4n)
if I did it correctly
