Off the top of my head i can tell that B) 3 and A) -1 are two possible roots, you can plug it into a calculator and situate put if there is more
the answer is 60 :) good luckStep-by-step explanation:
2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks
if 2000 is the 100%, how much is 640 in percentage off of it?
well

solve for "x"
-2[9 - (x + 7)]
-2[9 - x - 7]
-2[-x + 9 - 7]
-2[-x + 2]
-2[-x] - 2[2]
2x - 4
The answer is C.
1.3005 x 10^4
10 to the fourth power
