Answer:
The second choice is the correct one.
Step-by-step explanation:
20x^4 - 45x^2
GCF is 5x^2, so the factors are:
5x^2( 4x^2 - 9)
Now 4x^2 - 9 is the differencr of 2 squares:
4x^2 - 9 = (2x + 3)(2x - 3)>
Answer:
If a is 1.. we substitute one in every a in g(a)
4 * 1 + 16
4+ 16 = 20
g(a)= 20
f(20)
-16 + 20 = 4
and 4/4 = 1
so f (g (a)) = a

Answer:
-5/6=-5/-6=- 5/6
- 7/2=-7/-2=-7/2
Step-by-step explanation:
It's 11040 plants because 92 percent of 12000 is 11040. (Idk if this is the best reasoning but :/)
322 km/h = 322000 meters/h
Hope This Helps :)
