Question 979331: A rectangle has the width x and it's length is 10 greater hang he width. For what values of x the area of the rectangle is greater or equal to 24. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A rectangle has the width x and it's [sic] length is 10 greater hang he width. For what values of x the area of the rectangle is greater or equal to 24
------------
Area = x*(x+10)
Find x for Area = 24.
x*(x+10) = 24
(x+12)*(x-2) = 0
x = -12
=============
Ignore the negative solution.
---
x = 2
x >=2 --> Area >=24
=========================================
it's = it is
