Answer:
greatest velocity 6
Step-by-step explanation:
v=12t-6t2
dv/dt=0
12-12t=0
t=1
v at t=1=12-6=6
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
The answer to this question is Option C.
As stated in the problem, both programs being Math Master (75% to 87%) and Excel (73% to 81%) increased, therefore, meaning they are both effective as the average test scores increased. However, Math Master had a higher average test score increase compared to Excel, meaning it is even more effective.
Hope this helps :)

If you have 4 books and the total cost is $20, divide!
20/4 = 5
