Answer:
Step-by-step explanation:
Given,

we know,
(f-g)(x)=f(x)-g(x)
So, here we get
(f-g)(x)
=f(x)-g(x)
=
=
=
=
So, the answer is

What multiplies to 25 and adds to -10
-5 and -5
(x-5)(x-5)
(x-5)²
The correct factorization is
2(x-2)²
If he fills 5.9 bags for 18 hours, he will have filled a total of 106.2 bags
plane 1 travels 395 miles in 1 hour
plane 2 travels 422 miles in 1 hour
together, they travel (395+422) 817 miles in 1 hour
to have 2451 miles between then, they'd need to travel

so in 3 hours, they'll be 2451 miles apart
