Answer with Step-by-step explanation:
Let A is non-singular

We have to prove that
is unique.
Suppose B and C are inverse of A such that
and AC=I
By using property 




Hence, the inverse of A is unique.
Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!
The answer would me x + 6.01
And increase means to add so x + 61% = x + 6.01
Hope this helps

Answer:
8 x 10^8 is two million times as much as 4 x 10^2.
So I guess you could say it's 1,999,999 times larger.
