16) If Jim drove 168 mi in 4 hours, this means it takes him

this many hours to drive 1 mile. So if we multiply this by 504 mi:

Should be D. 2x65=130-20=110
Prism A has a volume of 36 m
Prism B has a volume of 288 m
The ratio of there lengths is that for every 1m in prism A, there are 8 m in prism B
Answer:
x = 5
Step-by-step explanation:
A quadratic equation:
f(x) = y = a*x^2 + b*x + c
Has a vertex in a point:
(h, k) such that:
h = -b/2a
and:
k = f(-b/2a)
And the axis of symmetry (this is the line that cuts the graph in two halves) is:
x = h.
In this case, the vertex is (5, -6)
Then the axis of symmetry is:
x = 5.
