First simplify the equation of parabola

in the following way:

.
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).
Second one is correct, that is an identity.
Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18
Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
The answer would be 39.84
Meter is 0.5 and the fraction is I think 1/2
Answer:
23 pets
Step-by-step explanation:
If Susy has 14 dogs and 9 cats she has 23 pets in all.
14 dogs
9 cats
14 dogs + 9 cats = 23 pets
Therefore, Susy has 23 pets.
