The basket player scores points for certain number of  minutes

Step-by-step explanation:

Given that " A basketball player practices jump shots "

Also given that she starts at 0 pts and scores 5 pts per minute.

Let x be the starting point of her and y be the points which she scores per minute.

Therefore the basket player scores points for certain number of  minutes

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
