If 5 = 6 , than 4 =7
so, line L // m
Let the second side be equal to x
Then the first side is x-5
The third side will be x-5-2 = x-7
Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42
3x=44
X= 44/3
Therefore the second sides length is 44/3
The first sides length is 44/3 -5 = 29/3
The third side is 44/3 -7 = 23/3
False. You only flip when the number you are multiplying/dividing is negative.
It's the slope-point formula:
We have:
Therefore, the slope
