Question 1136998


1.
{{{3x^2y-2xy+x-1 }}}

a) ​ Term:_{{{3 x^2 y}}} __,__ {{{-2 x y}}}__,__{{{x}}}___,_{{{1}}}____ 

​b) Coefficient:__{{{3y}}}__,__{{{-2y}}}__,___{{{1}}}__,_{{{1}}}___ 
​c) Degree of each​ term:_{{{2}}}__,__{{{1}}}__,__{{{1}}}___,_{{{0}}}__
​d) Degree of the​ polynomial:_{{{2}}}_ 

2.
 {{{d=240000mil = (24) (10 ^ 4) mil }}}

{{{s=4*10^4 (mil/h)}}}

{{{d=s*t}}}

{{{t=d/s}}}

{{{t=(24*10 ^ 4* mil )/(4*10^4(mil/h))}}}

{{{t=24 h/4}}}

{{{t=6h}}}

It would take {{{6}}} hours.
