1 x 19
29:
1 x 29
39:
1 x 39
3 x 13
So, because 39 has more than one set of factors, it's NOT a prime number.
In Piaget's theory of cognitive development, the use of metaphor and analogy is a sign of its formal operationality.
<h3><u>Describe formal operational.</u></h3>
Piaget's theory has four stages, the formal operational stage being the final and the fourth. Though Piaget does note that some people may never reach this stage of cognitive development, it starts around the age of 11 to 12 and lasts until adulthood.
The capacity to develop hypotheses and conduct systematic tests on them in order to find a solution to a problem characterizes the formal operational stage. In addition to being able to think abstractly, someone in the formal stage can comprehend the shape or structure of a mathematical problem.

Stereotypes such as women belong in the kitchen can be offensive to women due to the disrespect. Personally, I feel like gender-role stereotypes aren't helpful. Everyone has rights and are able to do the same type of work. Another, expecting a male to be "manly" and "strong". They shouldn't be expected to do all the dirty work either. It's a biased question so this is just my opinion.
