Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x = 
= 
= 
= 
= 
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.
Volume = base x width x height
Bill's Box is 8x20x6=960 cm^3
Martin's Box is 4x15x16=960 cm^3
Bill is right. The boxes have the same volume.
