X=4 because you combine 2+4 and subtract -6 then divide
Multiple both sides of the equation by V, and divide both sides by T.. You'll get PV/T=KT/V*(V/T)=K.
Answer:
C. 2(x + 10)(x - 10)
Step-by-step explanation:

different between A and B
=30-(-30)
=60
position of C from A or B
=(60÷3)×2
=40
possible value of c
=-30+40
=10
possible value of c
=30-40
=-10
8 because it goes from 1s 10s 100s so 8 is the answer
