D

Step-by-step explanation:

this is because d is the only one that fits the equation of x-y>5 because 9-1 gives u 8 which in real sense is greater than 5

in this question u actually substitute the values into place of x and y respectively as (x,y)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

answer is because 4×10=40

and 98×4= is 392

40,392
