From here, we define the variable x.
x = Number of the minutes left for the race
From here we can find the value of x
We have then:

Step-by-step explanation:
Answer:
Step-by-step explanation:
(a). = x ( 2x + 1 ) = <em>2x² + x</em>
(b). = 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>
(c). = 20x² + 22x + 6 - ( 2x² + x ) =
( 20x² - 2x² ) + ( 22x - x ) + 6 =
<em>18x² + 21x + 6</em>
