That means that, for example:
if your number is 49 the nearest whole number would be 50.
so by saying estimate the figure to the nearest whole number , they are basically saying find your nearest whole number.
X*y = distance
So the answer would be B.) xy miles
.57 I would assume but it really depends on how your scaling it
Answer: 0, 4, -9
Set the equation equal to zero.
x(x - 4)(x + 9) = 0
Solve for x by setting each factor equal to zero.
The factors in the equation are x, (x - 4), and (x + 9).
x = 4
x = -9
The zeros of the function are 0, 4, and -9.
