Answer:
2x^3 + 13x^2 + 26x + 16
Step-by-step explanation:
x(2x^2 + 9x + 8) +2(2x^2 + 9x + 8)
2x^3 + 9x^2 + 8x + 4x^2 + 18x + 16
2x^3 + 13x^2 + 26x + 16
C is your answer, you tell without solving
So let us set up the equations:
d = rt
d = 12t and plug in r = 12
so after t hours, the faster runner is 12t miles which is
for the faster runner.
d = rt
d = 8t plug in r = 8
so after t hours, the slower runner has 8t miles.
Now if you want to get the distance, simply subtract:
12t – 8t = 4t
Since we need to get the distance of ¼ mile, meaning:
12t – 8t = ¼
= 4(12t – 8t) = 4 x 1/4 -> multiply both sides by the lcd
to clear the fractions
= 48t – 32t = 1
=16t = 1
Get t by dividing both sides by 16 to isolate t.
So the answer is 1/16 which is about 0.0625.
