Answer:
a = 24
Step-by-step explanation:
The work done has the formula
W = F d
where the force and the displacement have the same direction
We can determine displacement using the distance formula
d = √[(5 - 0)² + (-1 - 4)²]
d = 5√2
Next, the force along the direction of the displacement must be determined
Use trigonometry to determine the angle θ
Finally, the work is calculated using the formula
W = F d / cos θ
substitute the values to get the answer

Step-by-step explanation:
Your question isn't complete but let's assume that you want to know the amount of time that she spends working on her homework.
Since we are informed that Ella practices piano for 45 minutes and that she spends m minutes longer working on her homework than she does practicing the piano, the expression to get the number of minutes that she uses on her homework will be:
= 45 + m
For example let's say that she spends 7 minutes more in her homework. Therefore, the total minutes spent on the homework will be:
= 45 + 7
= 52 minutes
