The answer of the factored polynomial is
(X+2)(2x+1)
Hector can bike 0.6 miles in 12 hours
Answer:
750 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
1 cent = 0.01
Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute.
$39.95 + 0.01x
Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute.
$9.95 + 0.05x
How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital?
This is calculated as:
Beetle cellular = Salamander digital
$39.95 + 0.01x = $9.95 + 0.05x
Collect like terms
$39.95 - $9.95 = 0.05x - 0.01x
$30.00 = 0.04x
x = $30.00/0.04
x = 750 minutes
A person need to use 750 minutes a month for beetle cellular to cost the same as salamander digital.

Answer:
-2/45
Step-by-step explanation:
Firstly, we get it out of the brackets:
-3/5+5/9
than we multiply in order to get even divisor, which is actually greatest common factor (gcf):
(-3/5)×9+(5/9)×5
-27/45+25/45=-2/45
