Answer:
D.
Step-by-step explanation:
f(5) = -25 + 40
f(5) = 15
((x^2)(y^2) - 9) *(3 - xy).
Note difference of two squares: (a^2 - b^2) = (a-b)(a+b)
(x^2)(y^2) - 9 = (xy)^2 - 3 ^2 = (xy - 3)(xy + 3). (Take note)
(3- xy) = -(xy - 3). (Take note of this also)
Your question said: ((x^2)(y^2) - 9) times (3 - xy),
Don't you think it should be divide? Would solve it as divide.
((x^2)(y^2) - 9) /(3 - xy) = (xy - 3)(xy + 3) / -(xy - 3)
= -(xy + 3).
Answer is (3). Solved it as divide. Using times gives none of the solution among the options.

She put the y in the same equation ....it was the mistake
She had to put the y in the other equation:
2x+ 22 - 10x = - 2
-8x + 22 = - 2
-8x= -2 - 22
-8x= - 24
x= 3
