2a^2 + 3a + 1
= 2a^2 + 2a + a + 1
= 2a(a + 1) + 1 (a + 1) ( a + 1) is common)) so it is
= (2a + 1)(a + 1) (answer)

<h3><u>The value of x is equal to -4.</u></h3>
-5 + 5x = -(1 - 6x)

-5 = -1 + x
Add 1 to both sides.
-4 = x
3 yds/sex*3600 sec/hr=10800yds/hr
10800yds/hr/1760yds/mile
=6.136363 miles/hr
