Answer:
-2
Step-by-step explanation:
(3×2²⁰-5×2¹⁹)/(-2⁶)³
=[(3×2-5)×2¹⁹]/-(2⁶)³
=[(6-5)×2¹⁹]/-2¹⁸
=1×(-2)
=-2
Answer:
x=3 and N is the mid-point.
Okay, so if N is the mid-point.
E D=15
E N=4 x -1
N D=4+ 2 x
6 x -3=15
Now get the 6 x by itself, so move the 3 over
So it would be: 6 x =18
So that would be 6 divided by 6 is x and then 18 divided by 6 equals 3
So, X equals 3

There are three major classifications of substances known as acids or bases. The Arrhenius definition states that an acid produces H+ in solution and a base produces OH-.

The Lewis theory is discussed elsewhere.
