Answer:
The answer would be 45
Step-by-step explanation:
120-60=60 which is how much he gets back from selling a bike. divide 2700/60=45 bicycles that have to be sold.
The equation in undefined when the denominator is equal to 0.
The denominator is (x+5) (x+11)
Solve for the x's to make the equations equal 0:
x+5 = 0
Subtract 5 from each side:
x =-5
x+11 = 0
Subtract 11 from each side:
X = -11
There are two answers -5 and -11.
