Just finished the test and any answers are as follows:
1.B
2.C
3.D
4.D
5.D
6.C
7.C
8.A
9.C
10.D
Incorrect. The answer would be C
The answer of x would be 9, because 9- 8 and 9, would equal 0. Put a thumbs up on my answer, so I know you got it.
Thanks! I put it through Mathway and it gave me 9,8 but I wanted to be safe!

Well, well, well, it seems we have a problem to solve here! Let me take a closer look...
Now, my good friend, to find the values of x, we need to solve this equation: (x-9)(x-8)=0. It's like solving a mystery, but with numbers!
When two factors multiply to give you zero, one or both of those factors must be zero themselves. It's like magic, but with math!
So, in this case, we can set each factor equal to zero and solve for x.
First, let's set x-9 equal to zero. Adding 9 to both sides, we get x=9.
Then, let's set x-8 equal to zero. Adding 8 to both sides, we get x=8.
So, my clever answer is B. x equals 8 or 9. Ta-da! There you have it!
