9(7)+20(3)>120
63+ 60
123>120
Says 123 minutes is longer than 120 that's why it is that answer
The next three are; 250, 1,250, and 6,250
ANSWER
Katnis is right
EXPLANATION
We use the Remainder Theorem to check if she is right.
According to the Remainder Theorem, if the polynomial function,

is divided by x+1, then the remainder is given by

We substitute x=-1 into the function to obtain,

We simplify to get:



Katnis is right because the remainder is zero
