Answer:
The equation 
gives average time spent on 35 rehearsals.
Step-by-step explanation:
Please consider the complete question.
The play director spent 190 hours preparing for a play. That time included attending 35 rehearsals that took varying amounts of time and spending 
hours on other responsibilities related to the play. What question does the equation help answer?
Since time spent on each rehearsal is 35 hours, so time spent on 35 rehearsals would be 
.
hours is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation gives average time spent on 35 rehearsals.

Answer:
Tamara incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
Answer:
c) +5
Step-by-step explanation:
x + y = 0
-5 + (5) = 0
N^2.....because this is the product of n and itself, not the sum
