Ration expressions cause excluded values wherever the denominator equals zero.
So, for any expression like
-5 is an excluded value if 
For example, the simplest one would be
In fact, if you try to evaluate this function at -5, you'd have
which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.
Deena drove:
585 miles/9 hrs
....which means
her average rate was:
65miles/hour
whereas
Kristen drove:
605 miles/11 hrs
....meaning
her average rate was:
55 miles/hour
Therefore, Deena drove at a faster rate than Kristen
5 (the sides) x 0.8 = 4 meters
Taking commen 2 in RHS
p = 2 (L+W )
Divide by 2 on both sides.
p/2 = L+W
Subtract W on both sides.
p/2 - W = L
or L = p/2- W
