8th Grade Identify the equations with X
3 as a solution.
Select all that apply
x + 3 = 4(x + 1) + 2
2x - 8 = 7 - 3x
3(x + 2) = 14 - x
4(x - 1) = 1x+ 5
5 – 2(x + 1) = x
6(– 4) = 2x

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
