The domain would negative infinity to positive infinity . Domain would be the smallest through the largest possibly value of X. If you also need the range it’s ( -4,infinity]
192 is the answer definately
100<28+12d
If she wants to collect over 100 then the 100 would be less than (<) what she collects. She is starting with 28 so whatever she collects is added on. Because she collects 12 a day, you would multiply 12 by however many days, d, she collects.
640 acres = 1 square mile
So we can say 1 acres =

square mile
So in 2.2 acres =

square mile
= 0.0034375 square mile
In general one mile = 1609.344 meters
So one square mile = 1609.344 * 1609.344 square meter
= 2589988 square meter
So 0.0034375 square mile = 0.0034375 * 2589988
= 8903.08375 square meter.
