Answer and explanation:
A quantitative variable is the one that can be measured numerically (in a discreet form or a function form). A qualitative variable are those that can´t be a numerical value but can be organized in groups.
Assuming these statements, we can determine that the variables in a), b) and h) are qualitative, while the variables in c), d), e), f) and g) are quantitative ones.

A. Tyrell's mistake was he did not open the bracket properly.
B. The correct simplified expression is 8 -6x.
From the question,
Tyrell simplified the expression 16 - 2 (4 + 3x) as 16 - 8 + 3x.
- Tyrell's mistake was he did not open the bracket properly. He was supposed to multiply the term outside (-2) by each of the terms inside the bracket (4 and +3x).
- The correct simplified expression is as follows
16 - 2 (4 + 3x)
First, open the bracket by distributing -2. We get
16 -8 -6x
Simplifying further, we get
8 -6x
Hence, the correct simplified expression is 8 -6x.
