To do this divide set miles (264) by hours (5.5) to give you 48. Then multiply you mph (48) by 7. So in seven hours, Shawna can drive 336 miles.
Answer:
14 and 6th I think correct me if I'm wrong this is for help not to cheat
40x+8x^2=0 can be solved for x (there are two solutions):
Divide all 3 terms by the greatest common multiple (which is 8x):
40x+8x^2=0
------------- -----
8x 8x
5 + x = 0 produces the root x = - 5.
Setting 8x = 0 and solving for x produces the root x = 0.
Be certain to check these results. substitute x = -5 into 40x+8x^2=0. Is the resulting equation true or false? Next, subs. x=-5 into 40x+8x^2=0. Is the resulting equation true or false?
