Answer:

||| First row: 11 -20 23 ||| Second row: -21 5 -24 ||| Third row: 6 9 -14 |||

Step-by-step explanation:

I wish I could explain it better, but all I did was plug it into matrix A on:

https://atozmath.com/matrix.aspx?q=minor

I pressed "find" without changing any of the settings, and scrolled down until I saw what was in the attached screenshot.

Each of the rows correspond to the first, second, and third answers, as you can see.

I hope this helps!

Answer:
x = 4

Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
= log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2

Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4

Hope this helps :)
