Answer:
A, C, D
Step-by-step explanation:
One way to answer this question is to use synthetic division to find the remainder from division of the polynomial by (x-3). If the polynomial is written in Horner form, evaluating the polynomial for x=3 is substantially similar.
A(x) = ((x -2)x -4)x +3
A(3) = ((3 -2)3 -4)3 +3 = -3 +3 = 0 . . . . . has a factor of (x -3)
__
B(x) = ((x +3)x -2)x -6
B(3) = ((3 +3)3 -2)3 -6 = (16)3 -6 = 42 . . . (x -3) is not a factor
__
C(x) = (x -2)x^3 -27
C(3) = (3 -2)3^3 -27 = 0 . . . . . . . . . . . . . has a factor of (x -3)
__
D(x) = (x^3 -20)x -21
D(3) = (3^3 -20)3 -21 = (7)3 -21 = 0 . . . . has a factor of (x -3)
___
The polynomials of choice are A(x), C(x), and D(x).
The improper fraction form of 4 2/3 would be 14/3, if that is one of the choices.
D = rt
We are given the rate r to be 15 mph.
We are given the time (in hours) to be 3.5.
We need to find D.
D = (15)(3.5)
D = 52.5 miles.

Answer:
4 units
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = 
h(a + b)
where h is the height and a, b the bases
here A = 46, a = 6 and b = 17, hence
46 = h(6 + 17) ( multiply both sides by 2 )
92 = h(23) ← divide both sides by 23 )
h = 
= 4 units
