It means to solve, or simplify the expression.

Let's give two examples.

1) 5 + 2²
    5 + 4
    9      <- We are trying to simplify/solve the expression to as far as we can. 
                 9 cannot be simplified, so the expression has been evaluated.

2) 4x - 5x + 9y
    -x + 9y          <- Can not be simplified any further so the expression has                                                been evaluated via. combining like terms.

ivolga24 [154]

Answer:

A

Step-by-step explanation:

Basically, this is an observational study because the researcher does not apply any treatment.

It's not an experiment because there is no experimentation involved. :)

It's not double-blind because in that case the researcher would have to apply something to two kinds of groups. one aware one the other not. not the case.

It's not D because  The observations are comparing two kinds of subjects and they are not looking for a cause and effect.
