Answer:
2nd
Step-by-step explanation:
the orange one
3x^2+x-2
3x^2 cant be broken down more because its a prime number. the only thing that can change is the x^2. the main difference between the blue and orange one is that the blue one has the second sign incorrect.
14-2a
Since 15 and 21 are not included: we will have
=15-2a-1
=14-2a
63
the first one is 9x bigger then the second one
so 7x9 is 63
