answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

pi x^2

step-by-step explanation:

pi times x squared
