I didnot known its answer.I am really sorry.
Inequalities require a sign of greater than, less than, greater than or equal to, or less than or equal to. It's never just a single number solution. It's always going to be a range of solutions
The answer would be
-63x^2y^3
D = T2 - T1
d = 9 - 14
d = - 5
T40 = 14 + 39(-5)
= 14 - 195
= - 181
