1/555 of a mile. I did this by figuring out how many seconds it would take her to walk a full mile and then got the answer for 1 second
Answer:
step 1. <2 + 40° = <1
step 2. <1 + 72° = 180°
step 3. <1 = 108°
step 4. <2 = 108° - 40° = 68°.
To keep it the same you need to divide 50 by 2 just like 60 got divided by 2. answer is 30:25

Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
Subtracting 8 from both sides of the equation gives
x^2 + 4x - 12 = 0
(x + 6)(x - 2)= 0
x = -6, 2 answer
