)- (2x2 +7x- 4)
As we have to subtract them so by simplifying:
"-" sign will alter all signs in the bracket
= 5x2 - 5x + 3 - 2x2 + 7x - 4
Now by adding same terms
= 5x2 - 2x2 - 5x + 7x + 3 -4
= 3x2 +  2x - 1

Answer:
This means that she will be 16.35 ft away from the rim in 15 minutes at this current rate. 
Step-by-step explanation:
What we are asked here is imply to state how long in terms of distance would be Arielle position after 15 minutes 
Now, 55 ft will take her 234 minutes 
x ft will take her 15 minutes

x = 3825/234
x = 16.35 ft 
This means that she will be 16.35 ft away from the rim in 15 minutes at this current rate.
