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.

(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 .

Answer:
C) 12.2 cm
Step-by-step explanation:
To find the area of a square, you multiply length and width, which for a square, are the same. So to find the length of one of its sides, you have to take the square root of the area.
Answer:
