Question

Pierce removes the plug from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by the expression 10x2 −17x + 3, where x is the time in minutes. Choose the appropriate form of the expression that would reveal the time in minutes when the trough is empty.
10(x − 3)2 − 1
10(x − 1)2 − 3
(5x − 1)(2x − 3)
10(0)2 − 17(0) + 3

Answer 1

Answer:

(5x - 1)(2x - 3)

10x^2 - 17 + 3 = (5x - 1)(2x - 3)

Answer 2

Answer:

C.(5x − 1)(2x − 3)
