Q2. The formula for finding the perimeter of a rectangle is shown below. P=2l+2w

What is that same formula rewritten for w in terms of the other variables?

A w=−P/2−l

B w=P/2−l

C w=−P/2+l

D w=P/2+l

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
