Answer: l = P/2 - w
Step-by-step explanation:
Perimeter formula for rectangle :
P = 2( l + w )
We have to write l in terms of P and W.
P/2 = ( l + w)
P/2 - w = l
Now, flip the equation and you'll get :
l = P/2 - w
Answer:55.73333333333
Step-by-step explanation:
Answer:
-24
Step-by-step explanation:
You just need to plug in 1, 2, 3, and 4.
10*4(1)-1=39
10*4(2)-1=79
10*4(3)-1=119
10*4(4)-1=159
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand, we have that if two lines are parallel then their slopes are equal.
Given the line AB:
the slope is 
Therefore, a parallel line will have slope 
Thus, the equation is of the form is: 
We substitute point
and find "b":

Finally, a line parallel to line AB is:
