A student has these expenses that total around 500 dollars and it asks how many degrees can you equate this to or something
Note: there is a picture of a pie divided in 5 parts and one part of the circle has an angle of 54 degrees
NOTE: There was a table with different expenses and when you add them up you will get 3,000. The book expense is 450. The question asks to find the angle of book expense in the pie chart so 450/3000 =a/360, then you cross multiply and the answer is 54 degrees

.*Asking for Factorization* H = 64 + 48t -16t^2
Process Below:
H = 64 + 48t - 16t^2
-16 ( t ^ 2 - 3t - 4) = H
Factor
-16 (t - 4) (t +1) = 0 (divide -16 on both sides)
(t-4) (t+1)
(t-2) (t+3)
