Am I correct or No?
natural numbers
c
b,c
b
d
c
ok for #1 id it D??
No.
It must be either a or c.
Ok, it's C then right?
Yes.
For the first question, we want to distribute the -2 to both terms inside the parentheses, so the expression becomes -2a - 12. Thus, the correct choice is -2a - 12.
For the second question, the number -22 belongs to the subset of integers since it is a negative whole number. It does not belong to the subset of rational numbers or irrational numbers since it is a whole number (-22.0) and can be expressed as a fraction (-22/1) respectively. Hence, the correct choices are integers.
For the third question, "6 times the difference of b and p" can be written as 6(b - p). This represents multiplying 6 by the difference of b and p. Therefore, the correct choice is 6(b - p).
For the last question, natural numbers are defined as positive whole numbers starting from 1. Since -22 is not positive, it does not belong to the subset of natural numbers. So the correct answer is No.
1. Wrong
2. I don't know.
3. Correct
