The length s of a side of a cuve is related to the surface area A of the cube by the formula s= square route of a/6. Which is greater: the surface area when A=27 or 2 1/2

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
