Simply the rational expression. state any restrictions on the variable. k2-k-2/k2-4k-5

We are given

Firstly, we will factor numerator and denominator

Restrictions:

we know that denominator can not be zero

so, we can set denominator =0

and solve for k to get restrictions

Simplification:

we can see that k+1 gets cancelled

so, we get

..........Answer

its a straight line parallel to the time axis

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
