The coefficient is: "1" .
____________________________________________________
Note: There is an "<u>implied coefficient</u>" of "1"; since "1", multiplied by any value, is equal to that exact same value; by convention, we eliminate the "1" as a coefficient.

Further explanation:
____________________________________
(x+p)(x−q) = x² − xq + px − pq ;
____________________________________
(x+p)(x−q) = {using "FOIL" → "First, Outer, Inner, and Last" terms}:
____________________________________
<u>F</u>irst: x*x = x² ;
<u>O</u>uter: x*(-q)= -xq ;
<u>I</u>nner: p*x = px ;
<u>L</u>ast: p*(-q) = -pq
_________________________________
(x + p)(x − q) = x² − xq + px − pq .

M=5
Positive 5 because a negative divide by a negative is a positive
All you have to do is divide 45 and 9
I kilometer is .62 miles
1/6.2= 60/X
Cross multiply
X= 37.2 miles
The answer is 15x-5
Hope this helps
