Well, 1 is in the tenths place, which means it's equal to 1 tenth, or 1/10.
Answer:
B
Step-by-step explanation:
Since the dot is not filled we can already take away c and d becuase it will not be equal to 2.
Next lets see which way its going.
The arrow goes right so it would be x>2
The answer that gives you that would be b.

Answer: Choice A. x^2+9</h3>
This is a sum of squares, which cannot be factored over the real numbers. You'll need to involve complex numbers to be able to factor, though its likely your teacher hasn't covered that topic yet (though I could be mistaken and your teacher has mentioned it).
Choice B can be factored through the difference of squares rule. Therefore, choice B is not prime.
Choice C and D can be factored by pulling out the GCF and then use the difference of squares rule afterward. So we can rule out C and D as well.
12 and 24.
Because
6=2*3
8=2*4
And 12=2*3*4
24=2*3*4*2
General rule: Try to find the factors of given numbers and multiply them in various cominations to get results.
The answer is 5 and 2/5. Hopefully it is correct!
