Answer:
Step-by-step explanation:
If v = plane velocity and c = air current, then:
v + c = 480

Answer:
(x+2)(x+8)=0
Step-by-step explanation:
the first term x² can only be factored by (x) times(x), and the last term 16 has factors of 16&1, 4&4 or 8&2. only 8 &2 have a sum of 10x (the middle term) so
(x+2)(x+8)=0
