1. Draw a model to show 1/2 of 1/2

If a =6, what is the value of 2a(3b + 5c)?

4+(2+x) can you me solve this problem

Marquise has 200 meters of fencing to build a rectangular garden. the garden's area (in square meters) as a function of the garden's width w w (in meters) is modeled by: a ( w ) = − w 2 + 1 0 0 w a(w)=−w 2 +100w what side width will produce the maximum garden area? meters
