The answer would be D, 12 units! :)
The letters in MATH can be arranged 16 ways. D.
To the convert 2/5 to a decimal it will be 0.40 because during when you do 5 do x20 so 1/5 = 0.20 and so on
for the percent it may be 40% but idk
The domain is the scope of the x values. In this case (-2,-1) is a hole, so x>-2 is one end of the domain, while (3,3) is defined. So the domain using interval notation is (-2,3] which can also be expressed -2 < x ≤ 3, answer option 1
