Answer:
B) h(x) = -1/4(x - 6)(x + 3)
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.
In this question:
Concave down, so , which excludes options c and d.
Roots at x = 6 and x = -3. So
So option B.

Answer:
The volume of a rectangular prism is
V = l · w · h
V= 252 cm3
h= 3 cm
l=5+W
W=x then l=5+x
V=(5+x)*x*3=252
3x^2+15x=252 cm3
the equation that models the volume of the tray in terms of its width, x, in centimeters.
3x^2 +15x=252 cm3
for width=7.5 cm
3x^2 +15x=3*(7.5) ^2+15*7.5= 281.25 cm3
281.25>252
it is not possible that the width is 7.5 cms
