Answer: for number 1 it is 9 number 2 is 24 number 3 is 4 and number 4 is 31
Step-by-step explanation: hope this is it
If the question is 25xsquare -9
then answer will be
(5x+3)(5x-3)
You know that 2 is the wrong answers because you can't multiply 9 by anything and get 12. So 12/2=6. multiply 9 by 6 and you get 54. So she got 54 correct answers
Basically you substitute 16 in for x.
f(16) = 3/4(16) - 5
f(16) = 12 - 5
f(16) = 7
