= i) Recall: The volume V (in cubic feet) of a hot tub is modeled by the
polynomial function V (x)
x3 - 10x2 + 11x + 70, where x is the
length of the side of the hot tub. Show that x + 2 is a factor of V(x).
Then factor V(x) completely.

answer: 20

step-by-step explanation:

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
