3(5y + 6) - 4

First, distribute so that it will make the solving easier.
(3)(5y) + (3)(6) - 4
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
15y + (3)(6) - 4
Third, multiply '3 × 6' to get '18'.
15y + 18 - 4
Fourth, subtract '18 - 4' to get '14'.
15y + 14

Answer: C)  15y + 14

Response variable: is a variable that measures an outcome or result of a study. In summary, we can say response variable are objects that respond to various changes made during an experimentation process.

Explanatory variable: This is a variable that practically explains the causes of changes in the response variables  

So consequentially, if we refer back to the asked question,

EXPLANATORY VARIABLE can be likened to be = Water Temperature

RESPONSE VARIABLE can be likened to be  = Weight

Categorical variables places the individuals into a category, while a quantitative variable is a numerical variable.

So consequentially, if we refer back to the asked question,

Water Temperature = Quantitative

Weight = Quantitative
