Question 38997This question is from textbook Beginning Algebra
: I need to find the speed on the side roads...I really am no good at word problems and need help...Thank you...
During rush hour, Fernando can drive 20 miles using the side roads in the same time that it takes to travel 10 miles on the freeway. If Fernando's rate on the side roads is 6 mi/h faster than his rate on the freeway, find his rate on the side roads. This question is from textbook Beginning Algebra

Question 39179: I am having some difficulty identifying the correct answer, it is actually multiple choice, but even the choices do not make sense.Here is the problem with possible solutions.
f(x)=2x^3+x^2+3x+8
List all of the potential rational zeros of the polynomial function. Do not attempt to find the zeros. The choices are:
a)+-2,+-4,+-8,+-1/2,+-7/2
b)+-2,+-4,+-8,+-16,+-1/2
c)0,+-1,+-2,+-4,+-1/2
d)+-1,+-2,+-4,+-8, +-1/2
